Function Code 5 ($05) - Write Single Coil

Description

Modbus function code $05 is a request to write a single coil. This will write a digital output of an RIO
configured as a slave.

Operating as a master

The function code of the response can be queried with the _MW command. If an exception occurred, the
exception code of the response can be queried with _MW1.

Example:

Normal Response

Exception Response

_MW results in $05

_MW results in $85

_MW1

contains

$01

$02

Ways to use Function Code 5 with Galil commands:

1. MB command in raw packet mode
2.

MB command with Modbus function code 5

Operating as a slave

The RIO will accept a write single coil request with a starting address ranging from $0000-$000F,
referencing digital outputs 0-15.

The RIO will respond with a Modbus packet that is identical to the packet it received.
