I am wondering if I can use an I2O module as a modbus master. I need to send some digital I/O to a PLC that can only act as a modbus slave. From the manual I understand how the Analog addressing will work. Does anyone know what addresses an I2O module will write the digital inputs to? I am thinking of using a 951EN-4012 module. Thanks for your help with this.
