MODBUS write status
The result of a write job is returned by the MODBUS slave in an acknowledgement message.
The result is returned as a hexadecimal word and can be saved as a status in the input area
of the CPU.
Name:
MODBUS write status
Memory area: The following options are available for the address range of the S7 CPU:
• DB: Data block
• Memory bit: Memory bit area
• Input: Process input image (PII)
DB No.: Specifies the DB number in the CPU if the "data block" memory area (DB) was
selected
Address [Byte]:
Input field for the byte number in the selected memory area.
Range of val-
ues:
See following table
Table 6- 9 Value range of the MODBUS write status
Code
Meaning
0x7002
Job executed without errors
0x8000
Job executed with error
0x8001 Illegal Function
After this error occurs, the S7 address of this write job is no longer read until the
next restart on the TIM.
0x8002
Illegal Data Address
0x8003
Illegal Data Value
0x8004
Slave Device Failure
0x8005
Message transferred but slave device busy with a different process (Acknowledge)
0x8006
Slave Device Busy with other process
0x8008
Memory Parity Error
0x800C
Wrong CRC check value in the response message of the slave
0x800D
Wrong net data in the response message of the slave
0x800E Wrong slave address in the response message of the slave
After this error occurs, the S7 address of this write job is no longer read until the
next restart on the TIM.
0x800F
Wrong function code in the response message of the slave
0x8010
No response (send timeout exceeded)

The "ModbusRead" object
The "ModbusRead" object
To map the data to be read between the MODBUS slaves and S7 CPU, the "ModbusRead"
object is available. A separate "ModbusRead" object is configured for each MODBUS slave.
