**08:05 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770221148030869):** (for the faltline)
**08:18 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770221886150879):** ive confirmed that the jail RW water is updating.. i just watched its value changing
**08:18 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770221888854009):** i'll keep looking
**08:20 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770222011130769):** The tanks at the plant
**08:20 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770222021408669):** effluent / RW tanks?
**08:20 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770222029136479):** Yes
**08:20 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770222032460019):** ok.
**08:20 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770222035038409):** the value isnt updating?
**08:20 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770222038205749):** or the trend isnt working?
**08:20 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770222050158379):** i cant run trends remotely so its difficult to check
**08:21 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770222087875339):** Value isn't updating. It updates on old scada
**08:21 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770222098895699):** ok, cool. i think i can work with that.
**08:21 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770222101183739):** thank you

**09:52 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227567095779):** @Kevin im trying to identify this PLC
**09:52 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227574432269):** DHP_ABPLC
**09:53 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227583866489):** do you know what the code folder may be called?
**09:53 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770227605882829):** the plc is the clearwell
**09:53 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770227613986289):** oh, wait
**09:53 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227615117949):** so.
**09:53 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227616942389):** yea.
**09:53 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227618258909):** no.
**09:53 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227631211489):** i found tags pointing to the clearewell PLC in old SCADA for level
**09:54 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227649003479):** but there are a dozen or so related tags for alarms and alarm setpoints for RW tank levels
**09:54 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227652263679):** that point to this PLC
**09:54 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227663780069):** the tags do not exist in the clearwell PLC
**09:54 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227690418919):** also curious why the level tags were set up pointing to this ABPLC instead of clearwell
**09:54 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227699764039):** ive fixed that.. and level is working
**09:55 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227712799749):** but they do not have setpoint control or alarm bits
**09:58 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227895751579):**

**09:58 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227904315819):** the alarm and setpoint tags resolve to values in whatever PLC that is.
**09:58 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227912903999):** but if level no longer lives there im afraid the alarms will not work
**09:58 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227919845459):** i need to sort out what happened
**09:59 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770227977242509):** if it helps, the analog input from the tank level transmitters goes into the clearwell plc
**09:59 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770227993000279):** ive updated the level values to use the clearwell PLC. and thats working
**10:00 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228009083319):** they were set up to read a different F8 address from this ABPLC previously
**10:00 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228022167739):** but scada will be incomplete if i dont link up the rest of the tags
**10:00 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228045443439):** copy!
**10:01 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228086355729):** alarms will not work and they will not have control over alarm setpoints
**10:01 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228103897179):** but level is now updating! so we are making progress
**10:02 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228133614259):** there are no alarm bits/setpoint tags in the clearwell PLC.. and no alarm logic either.
**10:10 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228622295309):** are they in the chem_rm plc?
**10:10 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228630561759):** yep i literally just confirmed that
**10:10 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228651804509):** but the level is no longer being messaged to that PLC.. im assuming thats why it stopped updating on scada
**10:10 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228659567839):** ah!
**10:11 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228664023259):** why
**10:11 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228670155739):** carrolo
**10:11 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228681554919):** last update was from them i think
**10:11 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228704684629):** I don't think they've updated the chem_rm plc
**10:11 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228710205509):** the clearwell PLC
**10:12 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228728461159):** yes, right. but I think that was a year or more agao
**10:12 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228733862869):**

**10:12 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228744003039):** indeed. im not sure.
**10:12 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228758393159):** this happened when I pulled the UF off the DH+ network
**10:12 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228758466869):** i cant confirm without being able to go online
**10:12 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228763115909):** ah
**10:12 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228765939669):** hm
**10:12 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228771488929):** you can go online using the old scada pc
**10:13 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228787224009):** oh. we have RUT on there?
**10:13 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228791539279):** yes
**10:13 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228794876209):** fantastic.
**10:14 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228845843519):** I'm sure you remember, but I'll give you the warning anyway. If you go online with those, and then offline, and it asks you to save, ALWAYS save.
**10:14 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228858314209):**

**10:14 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228860582189):** this is the MSG i need to confirm
**10:14 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770228871437179):** thanks for the reminder
**10:14 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770228890541299):** ok!
**10:25 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770229505091049):** when you have a second can you try to connect to the laguna machine? and let me know the RUT#? im struggling to find the right machine
**10:29 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770229784099629):** i found it
**11:23 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233022039899):** oops
**11:24 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233040050419):** that second message must have been added at some point.. on the branched rung
**11:24 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233047836339):** they are both executing at the same time
**11:24 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233060221289):** eventually this causes one of them to fail. and stay failed
**11:24 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233074136329):** i disabled the branched message and the first one started working again
**11:24 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233093626099):** i need to have the second one only trigger after the first one fails or succeeds
**11:25 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233111696329):** breaking apart the control word now to find the appropriate bits
**11:26 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770233164257259):** Ok
**11:26 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770233209242349):** I wonder why taking the UF off the network caused this
**11:27 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233225073569):** when re-enabling the second message it is working again.
**11:27 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233228527329):** i just dont know for how long
**11:27 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233235010899):** or what cauased them to collide
**11:27 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770233258547679):** Oh, so when I disconnected the cable it went into fail
**11:27 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233265316039):** MSG1 was locked out.. error message said disabled until link responds or something like that
**11:27 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770233270141589):** Then didn't recover
**11:27 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233272869369):** yeah
**11:28 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770233287313229):** Interesting
**11:28 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770233320942499):** Are alarms good now then?
**11:28 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233328783609):** im not done yet
**11:28 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233336582099):** but it should be back to normal
**11:29 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770233345225659):** i'll have to put the tags back to this PLC instead of the clearwell PLC
**11:29 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770233351169119):** Copy
**11:29 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770233357444009):** Thanks!
**12:18 [Mason Radke](https://slack.com/archives/C08JS6KDLBD/p1770236332825439):** ok! i feel like thats all sorted out
**12:51 [Kevin](https://slack.com/archives/C08JS6KDLBD/p1770238302907919):** Ah good!
