The "Modbusread" Object - Siemens SIMATIC TIM 3V-IE DNP3 System Manual

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.

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.

MODBUS write status
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)
•
Specifies the DB number in the CPU if the "data block" memory area (DB) was
selected
See following table
Value range of the MODBUS write status
Meaning
Job executed without errors
Job executed with error
Illegal Function
After this error occurs, the S7 address of this write job is no longer read until the
next restart on the TIM.
Illegal Data Address
Illegal Data Value
Slave Device Failure
Message transferred but slave device busy with a different process (Acknowledge)
Slave Device Busy with other process
Memory Parity Error
Wrong CRC check value in the response message of the slave
Wrong net data in the response message of the slave
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.
Wrong function code in the response message of the slave
No response (send timeout exceeded)
