I'm currently testting the T100MD with the Matrikon OPC server for Modbus.
I can't find a way to force one single output bit without forcing the whole row (the 16 bits)
The manual (page 5-3) seems to suggest that modbus function code 05 (force single coil) is supported.
A possible workaround would be: read the whole row --> do an OR calculation --> send the result back......if no better solution I will stick to this one but I don't like the idea of overwriting the 16bits each time..
Any suggestions ?
Cheers,
Christian
