**08:47 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759247271239509):** lets see what i can find
**08:52 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759247558750309):** yes.. leave as is.. power supply needed.
**08:52 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759247562209959):** simply replace the PLC
**08:57 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759247851007399):** Oh ok!
**08:58 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759247899688139):** Any power needed to be connected to the plc?
**08:58 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759247920218699):** likely.. yes.. let me see if i can confirm
**09:04 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759248268585019):** are there power terminals on the L320ER?
**09:04 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759248281321479):** it sounds like it gets power from the backplane.. and no external power is required.
**09:43 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759250634878249):** Still looking?
**09:44 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759250660874129):** no, i was waiting to hear back from you
**09:44 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759250666792409):** are there power terminals on the L320ER?
**09:44 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759250680070049):** it sounds like it gets power from the backplane and no external power is required..
**09:44 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759250684152149):** Yes
**09:44 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759250691807039):** MOD and SA
**09:44 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759250696931099):** thats what i remember also.
**09:45 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759250704337099):** and i feel like we need to power it.. but my reading is saying otherwise
**09:45 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759250729627739):** let me look at the manual for the L320ER directly
**09:45 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759250741654829):** Thanks
**10:10 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759252211437249):** I can't seem to add 1769 IO to a studio IO configuration
**10:13 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252412571019):** they are 1769 modules?
**10:13 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759252418125199):** Yes
**10:13 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252422116519):** is the l320Er 5069?
**10:13 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759252428102689):** Yes
**10:14 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252449168679):** ummm
**10:14 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252454184319):** im confused
**10:14 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252457504249):** standby
**10:19 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252774415219):** bad news.
**10:19 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252789379449):** moving from *L33E (5370)* to *L320ER (5380)*, your 1769 Compact I/O modules *cannot be reused directly* with the new controller. The L320ER is a *5380 series*, which requires *5069 Compact I/O* modules.
**10:20 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252804259649):** i dont know why this information wasnt more obvious when i first started looking into it
**10:21 [Kevin](https://slack.com/archives/C08HMJX8J4F/p1759252872786019):** Ok. Back to the drawing board
**10:22 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252961959359):** yeah that sucks
**10:23 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759252986477049):** what about converting that IO rack to Remote IO.. if there is a network adapter that works with 1769 modules
**10:24 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759253075324849):** *1769-AENTR*
**10:24 [Mason Radke](https://slack.com/archives/C08HMJX8J4F/p1759253086891329):** will turn that IO rack into remote IO that the L320ER can use
