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.
When not using flow control for serial communication between the display unit and device/PLC, start communication after the display unit starts up. Otherwise, it may cause a communication error.
When using [Ethernet (UDP)] and 1:n connections on models other than WinGP, if there is a device that is not connected, a communication error may occur even for the connected devices (Error code: R*xx083. xx indicates an undefined value. Replace * with H, J, K or M). To avoid this problem, stop communication scans for devices that are not connected. Turn ON the system variable ([PLC*]#H_ScanOffControl) to stop the communication scan. For details on [PLC*]#H_ScanOffControl, refer to the Reference Manual, "Bit Type - #H System Variables".
