A read request was made through sampling, extended D-script, Pro-Server EX, or some other function to a device with communication scan stopped. Turn OFF the appropriate bit*2 between LS9550 and LS9559 and start the communication scan of the connected device. |
RHAA073 | (Node Name): Illegal write request because this device has been off scan | A write request was made through a script, touch, Pro-Server EX, or some other function to a device in off-scan mode. |
A write request was made with a switch, D-script, extended D-script, Pro-Server EX, or other function to a device with communication scan stopped. Turn OFF the appropriate bit*2 between LS9550 and LS9559 and start the communication scan of the connected device. |
RHAA084 | (Node Name): Too many requests to write. The request was ignored. | A write operation was continued at timing which exceeds the processing speed of the communication driver. Example) For a connected device set up with a baud rate of 9600, if you continue to write with the same timing as tag scan counter updates. |
Check if a D-script or other setting has been specified which continues writing at fast speed. This error may occur when you use D-script with a bit that changes ON/OFF at a high rate (such as the LS9400 tag scan counter) to continually write to a device that communicates at a low speed (such as 9600 bps). |
RHAA085 | (Node Name): Too many requests to read. The request was ignored. | A read operation was continued at timing which exceeds the processing speed of the communication driver. Example) When reading continuously, with the same timing as tag scan counter updates, from a connected device that has a baud rate of 9600. |
Check if a D-script or other setting has been specified which continues reading at fast speed. This error may occur when you use D-script with a bit that changes ON/OFF at a high rate (such as the LS9400 tag scan counter) to continually read from a device that communicates at a low speed (such as 9600 bps). |
RHAA088 | COM1: The station number of Multilink function duplicates that of another device | The station number of Multilink function duplicates that of another device. |
Verify the station number and re-set it so it does not duplicate. |
RHAA089 | COM1: The address of the Multilink communication information is different from the other station | The address of the Multilink communication information is different from the other station |
Set the Multilink communication information address to the same address on the Multilink Network. |
RHAA090 | Response timed out from external device | Multilink communication surveillance timeout lapsed (60 seconds). |
Verify network. |
RHAA091 | COM1: Checksum error response for Multilink command | Checksum error occurs. |
Verify communication settings. |
RHAA092 | COM1: Failed to update the Multilink communication information | Failed to update the Multilink communication information |
Verify Multilink communication information and communication settings |
RHAA093 | COM1: Since cannot join to Multilink token, the request was unreceivable | Write request and read requests occurred (except for read requests that run all the time). Communication has failed for 2 hours. |
Add the display unit to the list of Multilink stations. Check if any display units are monopolizing the PLC for more than 2 hours. |
RHAA113 | Communication system assertion (****) | The device set up in the project is incorrect. Inside the brackets is the error content. |
Check the device set up in the project. |
*2 The setting range of the bit addresses for controlling running and stopping communication scans are internal device addresses LS9550 to LS9557. Each device/ PLC address starting from Bit 0 is assigned sequentially to each driver's device/PLC starting from the first unit.
Example, you can set the bit addresses of LS9550 to control communication scans for units 1 to 16 in Driver1.
LS9550
Bit 0: Scans ON/OFF Driver1's first PLC.
Stops the scan (scans OFF) of Driver1's first PLC by turning ON Bit 0. Turn OFF bit 0 to resume the scan.
You cannot stop the communication scan of a device specified with the System Area Start Address.However, if you are not using the System Data Area, you can stop the communication scan.
5.4.6 System Settings [Display Unit] - [System Area] Settings Guide
You can set the LS area with 32 bit addresses on some devices/PLCs.In this case, the bottom 16 bits are used for bit addresses controlling the communication scan.
When you turn OFF the communication scan, the displayed part's data will remain. However, if you change screens and then display the screen again, the part's data will not be displayed.

RAAE001 | Unable to restore history data. | If the history data file is damaged, the checksum of the history data file does not match, and the previous history data is abnormal, this error message appears. In this case, restart the display unit after clearing the history data. |
- |
RAAE002 | History data too big. Unable to restore history data. | If the volume of the stored history data file is larger than the size specified in the GP-Pro EX, and the previous history data is abnormal, this error message appears. Normally, this error does not occur but may occur when a history data file is exchanged. In this case, restart the display unit after clearing the history data. |
- |
RAAE003 | There is no history to restore. Unable to restore history data. | If no history data file exists and the previous history data file is also not normal, this error message appears. When the system fails while saving a history data file or a history data file is deleted, this error occurs. In this case, restart the display unit after clearing the history data. |
- |
RAAE004 | Recent history data is corrupted. Restoring previous history data. | If no history data file exists and the previous history data file is normal, this error message appears. When the system fails while saving a history data file or a history data file is deleted, this error occurs. In this case, restore the previously saved history data and then restart the display unit. |
