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.
Max Nodes Supported
