2.2.7.47 Registers 8401 to 8408: Indications from Modbus Slave Devices (Read Only)
These registers are write-protected. A write attempt will be rejected with exception code 02
(ILLEGAL_DATA_ADDRESS).
Data type: Indication
The following table shows the indications from the Modbus slave device 1 (8401). The indications from the oth-
er 7 Modbus slave devices (8402 to 8408) are in the same structure.
