Hello all.. I am pretty new to programming PLC's and have a few questions. We are using Mitsubishi PLCs and HMI's and I am writing a new program. We have a lot of pumps and actuated valves we will be controlling so a lot of outputs. My question is, if we are using the internal relays in the program to control the 24VDC coils to the pumps, can I use M1 and continue with M's until whatever number I want or do I have to use the M's with Hexadecimal as I do with the outputs. These are only used for the push buttons on the HMI's and I don't have actual inputs from the "real world."
For example:
-||-, -||-, -||-, and so on..
M1 M2 M18
Hope you all understand what I am asking. Thanks for your help.
