4.3.16 MASTER COMMS (Cont.)
MASTER COMMS CHANNEL CONFIGURATION
This display page, shown below, is called from the Operator/Confi g/Channels as described in section
4.3.3. A similar page appears in the Operator/Confi g/Maths confi guration described in section 4.3.11.
The actual picklists which appear, depend entirely on the type or model of instrument being read from. It
is assumed that the user knows which parameters are to be accessed.
The following sections describe
a. a typical input channel confi guration page with ‘Master Comms’ selected as Input Type, and a re-
corder or data acquisition unit as slave.
b. a typical input channel confi guration page with ‘Master Comms’ selected as Input Type for a slave
controller.
c. the situation where ‘User Defi ned’ has been selected as Parameter. In such a case, the user must
determine the required register number from the documentation supplied with the slave.
Note: For completeness, fi gures 4.3.16e, 4.3.16f and 4,3,16g show all possible confi guration fi elds.
The fi elds that actually appear are slave-model, and parameter dependent.
