M90-T communicating with V130

[Gabriel Franco]

Hello all, I must communicate an M90-T with V130.

I expected to use Modbus but just realized M90 doesn´t have Modbus.

I appreciate any suggestion

OK, let me ask it again. What I need is V130 to read (No need to write to M90) some MI´s (About 20) from M90-T, connecting via RS232. I cannot figure it out how so far. I´m considering to use ASCII format. I would appreciate any help

ASCII format would be another option, but it is tied to the SMS functionality. The M90-T does not support SMS.

The next fallback is to use the PCOM protocol and create a PCOM request using the V130. The PCOM protocol is available here:

This could be time-consuming if you are not familiar with serial protocols.

Thank you Simon, when I mentioned ASCII I meant PCOM. I´ll try today.
