I´ve got a problem with the initalisation of an Sony Ericsson GM29 GSM Modem. I have an M91-2-R34 Controller and just want to send sms. But every time the initalisation of the Sony E. failed.
SI 70 ist 2 and SI 180 is 1. I use the Example-prg. Simple SMS-send. It´s my first time with the U90 Ladder.
Could anybody give me a step-by-step instruction? Or have an idea, what i am doing wrong?
Thanks for every help

Looking for a piece of advice here. I put safety contact on wire that brings power to outputs, and noticed while testing that sometimes PLC loses serial connection with laptop when safety is activated. This made me wonder is any circuitry in controller powered from this side and is this good practice or should I change it?
Jazz controller is on the picture but I also noticed this on Vision.
I am wondering if anyone has used the Unilogic PLC's to cue videos on a separate television monitor? I am hoping to create a few hot buttons on a screen that start videos on demand not sure if this is possible by using just the PLC or if I would need some type of interface. Any advice would be appreciated.
