Hi, There.
We are currently looking to connect an Ignition to a PLC using two Moxa MB3180s as follows and get the values from the PLC in the Ignition.
With this, I have some questions and would like to ask them.
・Is it possible to connect Ignition and MB3180 by Modbus RTU, MB3180 to MB3180 by Modbus TCP, and MB3180 to PLC by Modbus ASCII, as shown in the figure, and get the values?
・Is the LAN cable connecting MB3180 to MB3180 a crossover cable or a straight cable?
・Which type of cable is used for the RS232C cable connecting the MB3180 to a PC equipped with Ignition, and which type of cable connecting the MB3180 to a PLC: a cross cable or a straight cable?
・In this case, what kind of addressing should I specify for Ignition? I browsed the Modbus Addressing site, but could not understand it very deeply.
Please let us know if there is any missing information.
If you have any solutions or clues to these questions, I would appreciate it.
Thank you in advance.
