Command channel

The Command Channel is used to read and update a selected set of device parameters.
This section describes the Command Channel from a generic point of view. The Command

Channel is available via several of the device interfaces: Ethernet Raw, EtherNet/IP, Web

API. There are differences depending on the possibilities each interface provides. The differ-

ences are described in the chapters about each interface.
It is possible to block changes via the command channel individually for each interface using

a setting in the interface configuration, as described in the Operating Instructions for Inspector

PIM60. This makes it possible to allow changes via a PLC oriented interface while blocking

changes via the Web API.

B.1

Command syntax

The tables below describe the different command types as well as ACK messages and their

syntax. The basic principle is that there are three major types of commands (sINT, gINT, and

aACT) and some special commands.

Table B.1

Command syntax

Explanation

Command format

Get protocol version that is supported by the ad-

dressed device

gVER

Set device mode (0 = Run, 1 = Edit)

sMOD [mode]

Get the current device mode from the device

gMOD

Set “integer” parameter in the device

sINT [identifier] [arg1] [arg2] … [argN]

Get “integer” parameter from the device

gINT [identifier] [arg1] [arg2] … [argN]

Get "string" parameter from device

gSTR [identifier] [arg1] [arg2]

Action commands

aACT [identifier] [arg1] [arg2] …

[argN]

Trig an image acquisition and analysis

TRIG

Retrieve the latest available Ethernet Result Output

string

gRES

Retrieve the latest statistics from the device

gSTAT
