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.

4. Configuring the FieldServer as a Gardner Denver Auto Sentry ES/RS2000
Client

For a detailed discussion on FieldServer configuration, please refer to the
FieldServer Configuration Manual. The information that follows describes how to
expand upon the factory defaults provided in the configuration files included with the
FieldServer (See “.csv” sample files provided with the FieldServer). This section
documents and describes the parameters necessary for configuring the FieldServer
to communicate with a Gardner Denver Auto Sentry ES/RS2000 Controller.

1.04 Data Arrays/Descriptors

The configuration file tells the FieldServer about its interfaces, and the routing of data
required. In order to enable the FieldServer for Gardner Denver Auto Sentry
ES/RS2000 communications, the driver independent FieldServer buffers need to be
declared in the “Data Arrays” section, the destination device addresses need to be
declared in the “Client Side Nodes” section, and the data required from the servers
needs to be mapped in the “Client Side Map Descriptors” section. Details on how to
do this can be found below.

Note that in the tables, * indicates an optional parameter, with the bold legal value
being the default.

indicating that all available data is
polled for.

Data will be stored as follows:

4.1.5. Map Descriptor Example 2 - Polling only specific data items

Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function, Node_Name, Gar_cmd, Gar_data, Scan_Interval
GD_MBA1, DA_Hourmeter, 0, RDBC, Node_1, Service_Data, Hourmeter_total, 1.0s
GD_MBA2, DA_Oper_Mode, 0, RDBC, Node_1, Operating_Mode, Oper_mode, 1.0s
GD_MBA3, DA_Motor_Amps, 0, RDBC, Node_1, Operating_Data, Motor_current, 1.0s

Note the active Read Block Continuous map
descriptor function responsible for polling the
Controller.

The Gar_cmd is set to indicate Operating
Data must be polled for.

The Gar_data field is set to
“Motor_current” indicating that only this
data item will be stored.

4.1.6. Map Descriptor Example 3 - Polling all data and isolating specific data items

Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function, Node_Name, Gar_cmd, Gar_data, Scan_Interval
GD_MBA1, DA_Service_Data, 0, RDBC, Node_1, Service_Data, All, 1.0s
GD_MBA2, DA_Oilage, 0, Passive_Client, Node_1, Service_Data, Oilage, ­GD_MBA3, DA_Hourmeter, 0, Passive_Client, Node_1, Service_Data, Hourmeter_total, -

GD_MBA4, DA_Oper_Mode, 0, RDBC, Node_1, Operating_Mode, All, 1.0s
GD_MBA5, DA_Oper_State, 0, Passive_Client, Node_1, Operating_Mode, Oper_state, -

GD_MBA6, DA_Oper_Data, 0, RDBC, Node_1, Operating_Data, All, 1.0s
GD_MBA7, DA_Disch_Temp, 0, Passive_Client, Node_1, Operating_Data, Discharge_temp, -

Note the use of the passive map descriptor function. This map descriptor
does not poll but receives data from the active map descriptor since the
Gar_cmd and Node_Name fields match.

Note, the Gar_cmd
indicates polling for
Operating data.

Note that a specific data item,
“Discharge_temp” is isolated here by
still using the same Gar_cmd as the
active map descriptor.

Appendix 1. Advanced Topics

Appendix 1.1. Can I use only Passive Client mapdescs ?

No. A passive client map descriptor must be used after an active RDBC map
descriptor. The driver uses the active map descriptors to poll the Controller and then
searches for Passive Client map descriptors with matching Node_Name and
Gar_Cmd fields. It then stores the data items as specified by the Gar_data field from
the data collected by the preceding active map descriptor.

Appendix 1.2. Data length of specific polls versus “All” data polls

The length of the data packet retrieved from the Controller during a poll is always
fixed for each of the three types of data polls. When specifying a specific Gar_data
item on a RDBC active map descriptor, the driver still gets all data of Gar_cmd type
from the controller in a single poll, but only stores the data item in question.
