Check the specifications of the External Device.•When using this driver at a communication speed of 38400 or more, there are the following limitations as listed below.•The DH-485 driver of Rockwell Automation, Inc. cannot be used simultaneously.•SIMATIC S7 MPI direct driver of Siemens AG cannot be used simultaneously.•This driver (communication speed: 38400 or more) cannot be used with both COM1 and COM2.•When this driver is used, the execution time of the logic function in the Display may be longer.•When LT-4*01TM / LT-Rear Module is included in the connection configuration, Polarization resistance of the LT-4*01TM / LT-Rear Module is set to stabilize a signal level in the communication line. (Polarization resistance is different from terminal resistance.)•When one LT-4*01TM / LT-Rear Module is used, set "560" (default).•When two or more LT-4*01TM / LT-Rear Modules are used, set "560" (default) for one of the LT-4*01TM / LT-Rear Module and set "None" for the other.•Polarization resistance can be set in offline mode only. To display the setup screen, touch [Device/PLC Adjust] of the [Peripheral Settings] tab in the offline mode.ExternalDevice(Master)Display(Slave)Maximum number of connections: n*1ExternalDevice(Master)Display(Slave)Display(Slave)Display(Slave)MODBUS SLAVE Driver GP-Pro EX Device/PLC Connection Manual5�Ethernet (TCP)•Connection example 1:1•Connection example n:1*1The number of Displays (Slaves) you can connect depends on the External Device.
