Vidmas30 Posted December 18, 2015 Report Share Posted December 18, 2015 Good day, everybody, Never been in such situation before: communicating with Omron PLC's. To minimize number of modbus operations Omron programmer gives us information about control bits in 16-bit registers. We are reading and storing them in Unitronics 16-bit registers (MI). But now came thought that Vision MI max value is 32767(in case 15 of control bits are set to 1). But if all 16 bits are set, then value becomes 65535. All messed up in the head.. Vision is using signed 16bit registers and Omron unsigned, I think. Do we have to use DW or ML variables in such case? Thank you for help.
