InsiteIG model 4000 which is the device I use to be slave with Micrologix 1400, Its has an auxiliary port (using both ASCII and RTU)and the maintainance port (DB9 serical cable to Laptop) (only ASCII) !
Do you think If I can find out a auxilary to serial dapter, I able to connect the device (auxilary port) to PLC (Serial port), I can read information from the device ??
I use Ethernet to connect PLC and HMI by a modem !
