1 GARDNER DENVER AUTO SENTRY ES/RS2000 DESCRIPTION
The Gardner Denver Auto Sentry ES/RS2000 driver allows the FieldServer to transfer data from devices over either
RS-232 or RS-485 using Gardner Denver Auto Sentry ES/RS2000 protocol. The driver can be configured to
communicate with ES Controllers with software versions V2.0X, V2.1X and RS2000 Controllers with software
versions V4.0X
The client driver implements the following functionality:

Polls controllers for service and maintenance data.

Polls controllers for operating mode data.

Polls controllers for operating data.
The driver can poll up to 8 units connected to one ES/RS2000 Controller. It always sets the active unit on the
ES/RS2000 Controller before polling for data even if consecutive polls are for the same unit. This is done to prevent
synchronization problems.
Gardner Denver ES/RS2000 Controllers implements three message types for which the driver can poll. The driver
does not validate the message data fields for correct values although it does validate data field lengths For
example, shutdown codes reported by V2.1 ES Controllers range from 0 to 27. If a code of 28 is reported, the driver
will not flag it as an error since codes have to be interpreted by the operator. However, a message length longer
than 2 digits will be reported as an error.
