5.3.3.5. Loading the measurement value/status
Request is made to load the pressure value, status and setpoint information of equipment connected
to each channel.
Request
: CH
(CH: 1~5)
* The setpoint indicates the allocation of the setpoint output to the designated measuring unit (ch).
* About designation of CH:5
Processed as an effective command only when the combination mode is designated.
The displayed value is transmitted in response as the pressure value.
(In the combination mode, CH:1, 2 is transmitted in response only within the actuating range of
IG2/IG4/CCG or PG.)
Status (SH, SL) reflects the value of the CH1: IG2, IG4 status.
Setpoint status (STSH, STSL) reflects the set status of Ch: 1, 2.
