GP-Pro EX Device/PLC Connection Manual
- To make the communication settings correctly, confirm the serial interface specifications of Display unit for [SIO Type].
We cannot guarantee the operation if a communication type that the serial interface does not support is specified.
For details concerning the serial interface specifications, refer to the manual for Display unit.
- When an External Device is sending a packet at the start-up of the Display if the low communication speed such as "2400" is specified for [Speed], the parity error may occur.
- To make the Ethernet communication settings, avoid setting of [8000 to 8019] for the port number of the Display unit. The Display unit’s system uses [8000 to 8019] in the initial status.
The port number that the system uses can be specified in [Ethernet Local Settings] in the Offline Mode. For details, refer to [Ethernet Local Settings] in Maintenance/Troubleshooting.
In the [Ethernet (TCP)] driver settings, increasing the [Timeout] above the initial value could cause a timeout error before the set time elapses.
Changing the driver from [Ethernet (TCP)] to [Ethernet (UDP)] while the [Port No.]'s [Auto] check box is selected could cause an error to appear. Please clear the [Auto] check box before changing the driver.
- When WinGP and other applications are running on IPC or PC/AT compatible units, enter a [Timeout] value larger than the time required by the other applications. If not, a timeout error or receive data error may occur.
