EYFR03 User Manual 68 of 110 v1.6.0Chapter 6: Atlas Copco Open Protocol 20 January 2020IntroductionThis chapter describes the support for the Atlas Copco Open Protocol in the EYFR03.Command MIDs and revisions referred to in this document are from the Atlas Copco OpenProtocol Specification release 1.3 revision 1.Using Groups with Atlas Copco Open ProtocolThe group features of the EYFR03 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 inone of the job commands, add 300 to the group number. To represent groups, you must use arevision 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, and3 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 subscriptionwill give a message with “job number” 305 when group 5 is selected in the unit.Configuration OptionsFigure 54: Main Menu - NetworkSettingsFigure 55: Network Settings Menu -ACOPFigure 56: ACOP SettingsKeep AliveRange: 0 to 3600 secondsDefault: 30 secondsThis setting controls how long in seconds the unit will keep a connection open without anycommands. This value is recommended to be more than twice the rate at which the client willsend keep alive packets to ensure the connection is not closed due to a single missed keep alivepacket. For example, if the client is configured to send keep alive packets at a 20 secondinterval, 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 setto 0, the unit will not close an ACOP connection due to inactivity.Ack TimeoutRange: 0 to 3600 seconds
