program version

1 post in this topic

Hi all, according to my last post http://forums.mrplc.com/index.php?showtopic=20555 i decided to change the 214 CPU into 226 CPU the PLC and it's modules(DO-222, and AI-231). i would like to know if there are any problem with transferring the program from the S7-214 CPU to S7-226 CPU? P.S i noticed that the 214 CPU is an AC/AC/AC and the Expansion module 222 DO as well AC output, and i couldn't find 226 CPU AC/AC/AC, the only options is DC/DC/DC or AC/DC/Relay, and is there Analog input on the 226 CPU? does it matter the type of the inputs/outputs, and how does it influence on the system? Thanks in advance, Best Regards, Greg. Edited by Greg
