Technical support / T100MD888+ as ModBus slave
« on: March 31, 2009, 04:36:28 AM »
hi!
I use T100MD888+ and trying to make communication betwen this one and another PLC that has ModBus. When T100MD888+ is master in the network everything is OK, but when it is slave it doesn't work. Is there anyone that was made this before to help me. And is there anyone that can say me what is the adress of the holding registers that i can read?
Thank you in advance!
