New page

This driver allows to connect local I/O with the ''S7-SoftPLC'' via Ethernet / Modbus TCP. The driver supports the Modbus TCP function codes listed in the chart below. If a slave is supposed to run with the ''S7-SoftPLC'', it should be verified, that it supports the listed Modbus functions. If possible the Modbus function Read/Write Registers (0x17) should be used, since it executes reading and writing in one frame. If a slave does not support this funciton, it has to be created as two slaves. The first configuration reads the inputs, the second writes the outputs. Since this isn't very efficient, the function Read/Write should be preferred. Additionally the driver installs a Status SFC/FC, to monitor the status of the Modbus TCP connection.

'''Status word'''

If successful the BR of the status word is set, OR, STA and /FC are zero.

If failed the BR, OR, STA and /FC of the status word are zero.
