1.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. Thus the driver permits the transfer of current pressure information, Gage status information and the processing of Gage verification information.

The driver is capable of providing active Client and passive Server support. An active Client polls for data and processes responses, it is not capable of processing unsolicited messages from the remote device. A passive Server can respond to polls but is not capable of sending unsolicited messages reporting change of state or other information.

When configured as a Client it is important the digital Gage is configured correctly and that it is left in an operational mode where it can respond easily to the commands sent to it. If a user, were to operate the Gage from its front panel and leave it in a configuration state, awaiting input from a user, then the Gage would be incapable of responding to commands from the FieldServer. The driver cannot write to the digital Gage. Thus alarm set points and other configuration tasks cannot be performed using a FieldServer.
