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
