IMPLEMENTING THE OMRON HOST LINK PROTOCOL (VB.NET) in Other Omron Software Posted 26 Jul 2018 Hi Garry, I have a new question regarding the programming of another model of PLC. This time it is an OMRON NX1P2 PLC. Can I use the same method to communicate with this PLC? ie using host link with C-mode commands to read the addresses on the PLC? Thank you!!
