Table 3-69 Process data acquisition block types
If a setpoint is simultaneously configured with the same process data
block for several OP2, then it cannot be simultaneously changed from
each OP2.
The setpoint can be changed at that OP2 at which is was selected by first
depressing the "CHG" key. As long as the setpoint is selected, and
"CHG" is running, data cannot be changed at other OP2 devices. If an
attempt is made to change the value, the user obtains an appropriate
system message.
Further information
on the OP2, refer to the OP2 User Manual.
The setpoint function blocks have connections XAL and ENI, which can
be used to display an alternative setpoint input at the OP2; but this
setpoint cannot be changed. You will find configuring examples for this in
the Reference Manual Function block library for setpoint blocks (DISS...).
3.20.3.3 Acquisition blocks for binary values (only OP2)
A maximum of 32 binary values can be configured at each OP2. A binary
value block must be configured for each binary value. In this case, using
one block, the same binary value can be assigned to several OP2
devices simultaneously under the same binary value number:
• DIS
Reference to the display system, configured using @DIS.
• ST1, ST2
USS station addresses of the OP2 operator control unit, at which the
binary value can be selected.
