[. . . ] Selection can be accomplished from the front panel (see Section 3. 4. 4. 3) or remotely by using the "MSGFMT" program message. The default is the classic program message format to allow downward compatibility with existing host software. The basic commands are similar for both the classic and enhanced formats, but the usage, syntax, format and status reporting are different. The PPC2+ enhanced program message format also includes new additional common program messages that are required in every device that complies with the IEEE Std 488. 2. These addition common program messages are covered separately in Section 4. 6. 1. 4. 3. 1 CLASSIC PROGRAM MESSAGE FORMAT The classic program message format is downward compatible with the previous PPC2 program message set. However, several PPC2 functions are not supported by PPC2 and neither are their corresponding commands (see DEVICE, DPG, ISO, PPC, HOLD, TOUT, TS, CONFIG10). This format is recommended only if you need downward compatibility with older PPC2 controllers. Each program message sent is also a query. You can only send one program message to the PPC2+ at time. After sending any program message, you must wait for the PPC2+ to reply before sending another program message. This reply will contain data, or a numeric error message if the program message was invalid. You must wait for this reply before issuing another program message to the PPC2+. This insures that the PPC2+ has completed the program message. Most remote program messages will return a reply within 500 ms except: PR, PRR, SR, ATM, RATE Up to 2. 0 seconds to allow a new measurement. The syntax and format used for each program message in the classic mode is listed next to the keyword `Classic:' in each program message summary in Section 4. 4. 4. 4. 3. 2 ENHANCED PROGRAM MESSAGE FORMAT This enhanced program message format uses the IEEE Std. 488. 2 format, syntax and status reporting and is recommended for new applications. If an error is reported, the error is put into an Error Queue and the "ERR?" query program message can be used to get a text description of the most recent error. If you are using the IEEE-488 port, the service request line can be setup to be asserted if this occurs (see Section 4. 5. 2). There are two possible program message types for every program message. Each of these two types starts with the same basic text referred to as the program message header. Page 79 ©2001 DH Instruments, Inc. PPC2+TM Operation and Maintenance Manual 4. 3. 2. 1 ENHANCED PROGRAM MESSAGE USING THE COMMAND TYPE The COMMAND type of program message executes a process and can additionally send data to the PPC2+ in the form of comma delimited arguments. This data is usually a setting of some sort that is stored in the PPC2+. If data is specified, it must be preceded by at least one white space from the program message header and be within the range and format described in the program message description. [. . . ] Whether pressure is being measured relative to absolute zero or vacuum (absolute mode) or relative to atmospheric pressure (gauge mode). Pressure adder, used to offset an RPT range or barometer in calibration. Pressure multiplier, used to adjust span of an RPT range or barometer in calibration. The rate of change of the current pressure. [. . . ]
