10.5 Simulation of digital outputs
It can be helpful, particularly during startup or service, to check the down
stream system components and processes by simulating and enabling the digi
tal outputs. For this purpose, the digital outputs of the MP85A process con
troller can be enabled/disabled via software commands.
The composition of the data word that is transferred for enabling/disabling the
digital outputs depends on the configuration of the data word bits on the digital
outputs.
You can view the status of the digital inputs and outputs via the “Measured
value display” menu.
Example: Enabling digital output 1
► Set digital output 1 in the “Digital outputs” menu to “Data word bit 0” (posi
tive circuit logic).
► Sending to address SDO 2320 Index 0 (hex) => 1 (dec) via a software com
mand (e.g. “SDO terminal”) sets digital output 1 to High.
► Sending data word 0 (dec) to address SDO 2320 Index 0 (hex) disables
digital output 1 once more.
10.6 Parameter sets (measurement programs)
The MP85A process controller offers you the option of using 31 different mea
surement programs (parameter sets) in the internal flash memory and saving
them so they are power failure-proof. A further 1000 measurement programs
can be saved on the optional (MMC/SD) memory card.
Important
You can only switch or load parameter sets when a process has ended, not
during a measurement. You can only start the next process once parameter
set switchover is complete (also see section 10.1, Machine control system).
Parameter sets saved to PC cannot be used by the device or software for
ongoing operation. They must therefore be saved in the flash memory or on
the memory card.
