Introduction The FX3G and FX3U PLCs provide the facility to add ADP modules to the left-hand side of the PLC such as the FX3U-4AD-ADP (4 channel analogue input module). The data for these modules is automatically placed into specific data registers in the D8000 range....

Introduction It is often the case that a PLC will be linked with an HMI and it is very helpful if both items can share the same variables list (Tag list or I/O list). Here we explain how this can be done. Design Considerations Firstly, it must be understood that the...
