Global 400 User Manual 53 of 85 v1.1 revision 1
Chapter 5: Atlas Copco Open Protocol 2 February 2016
Introduction
This chapter describes the support for the Atlas Copco Open Protocol in the Global 400.
Command MIDs and revisions referred to in this document are from the Atlas Copco Open
Protocol Specification release 1.3 revision 1.
Using Groups with Atlas Copco Open Protocol
The group features of the Global 400 are not defined directly in the protocol specification.
Instead, they are represented as jobs when using this protocol. To reference a group instead of a
job in one of the job commands, add 300 to the group number. To represent groups, you must
use a revision that uses 4 characters for the job number.
For example, sending MID 0038 Select Job with a job number of 7 will select Job 7 in the unit.
Sending MID 0038 with “job number” of 306 will select Group 6 in the unit. If groups 1, 2, and
3 and jobs 10, 11, and 12 are defined in the unit, MID 0030 Job ID Upload request would return
“jobs” 10, 11, 12, 301, 302, and 303 in the reply. Similarly, the MID 0034 Job Info subscription
will give a message with “job number” 305 when group 5 is selected in the unit.

Keep Alive
Range: 0 to 3600 seconds
Default: 30 seconds
This setting controls how long in seconds the unit will keep a connection open without any
commands. This value is recommended to be more than twice the rate at which the client will
send keep alive packets to ensure the connection is not closed due to a single missed keep alive
packet. For example, if the client is configured to send keep alive packets at a 20 second
interval, the keep alive setting on the unit should be more than 40 seconds.
The keep alive function can be disabled by setting the keep alive to 0. When set keep alive is set
to 0, the unit will not close an Open Protocol connection due to inactivity.
Ack Timeout
Range: 0 to 3600 seconds
