Hello to all. I am new to PLC’s as well as this forum so if I make any mistakes please forgive me.
I am having an issue using the 2080 OF2 output module with the Allen Bradley Micro 820 PLC. I am trying to use the analog output current pin to send a 4-20mA signal. I understand from the data sheet and various sources that the range for 4-20mA is analog range of 13107-65535. I know how to configure the output module and the PLC. My issue lies with the code. How exactly should I put a, say for example 4mA on one of the pins? I have seen various sources use scaler and MOV instructions and ANYtoREAL instruction. However I am not measuring 4mA on the pin I am getting nothing. What kind of code should I write in order to put the mA output on one of the pins? I am simply trying to output 4-20mA on the output module. Thank you for all suggestions and I apologize for any rookie misunderstandings I may have. Thanks!
