FS-8700-101_Setra Model 370 Digital Pressure Gage Manual 1. Page 3 of 23 Setra Model 370 Digital Pressure Gage Description The ‘Setra Model 370 Digital Pressure Gage’ driver allows the FieldServer to transfer data to and from devices over either RS-232 or RS-485 using the ‘Setra Model 370 Digital Pressure Gage’ protocol. The FieldServer can emulate either a Server or Client. The driver implements a subset of the commands and responses that an actual Setra Model 370 Digital Pressure Gage is capable of.

FS-8700-101_Setra Model 370 Digital Pressure Gage Manual 3.1. Page 6 of 23 Hardware Connection Tips / Hints The following notes are extracted from the Setra 370 Operator Manual. The Setra Digital Pressure Gage implements the majority of the RS-232 communications standard, but does not provide handshaking lines (such as busy, DSR, or DTR). The four lines which must be connected are diagrammed below, along with the pin layout of the female connector on the back of the gage.

FS-8700-101_Setra Model 370 Digital Pressure Gage Manual 4.4.4. Page 10 of 23 Map Descriptor Example #1 – Read Pressure. In this example a Map Descriptor is defined which controls the task of reading pressure data from the Setra Model 370 Digital Pressure Gage. The task gets performed every 5.0 seconds. When a response is received the data is stored in the Data Array called DA_PRESSURE stating at element zero (the offset).

Page 11 of 23 Map Descriptor Example #2 – Read Status In this example a Map Descriptor is defined which controls the task of reading status data from the Setra Model 370 Digital Pressure Gage. The task gets performed every 5.0 seconds. When a response is received the data is stored in the Data Array called DA_STATUS stating at element zero (the offset).

In this example a Map Descriptor is defined which controls the task of reading verification data from the Setra Model 370 Digital Pressure Gage. The task gets performed every 5.0 seconds. When a response is received the data is stored in the Data Array called DA_VERIFY stating at element zero (the offset).

FS-8700-101_Setra Model 370 Digital Pressure Gage Manual 5.3.3. Page 16 of 23 Server Map Descriptor Example. This Map Descriptor defines a capability of the FieldServer to respond to a poll for an immediate Pressure Print (Command Code = ‘P’). When the poll is received, the driver inspects 5 consecutive array elements starting at offset 0 in the Data Array named DA_PRESSURE. The contents of the 5 elements are defined in Appendix A.1.1.

FS-8700-101_Setra Model 370 Digital Pressure Gage Manual Page 18 of 23 Appendix A.2. Gage Pressure Units The driver does not report status and pressure reading units as text strings. Rather, the driver reports and index number. Use the index number and the table below to determine the units being reported. Index # 0 1 2 3 4 5 6 7 8 9 10 Meaning The Units field could not be interpreted correctly / there were no units reported / the units reported were not part of the following list.
