Bit 1: You can inform the IP 244 whether you want it to read 30 or 60 values each via channel 13
(only when special function is selected).
TĆno. 15, byte 6 (duration of acquisition) presets the total time of the readĆin procedure. The
following applies for bit 2
1
= 1 in the main control byte 3: the minimum duration of
acquisition is 3 seconds, otherwise (bit 2
1
= 0) 6 seconds.
Bit 4: Valid for all controllers with cooling outputs: the controller parameters are adapted internally
to the temperature of the coolant (e.g. air, oil water). If bit 4=1 the IP takes message 15 byte
17 as the coolant temperature, otherwise the temperature measured by the
compensationĆPt 100 or operation without thermocouples 0 °C (32 °F) is selected.
Bit 5: Continuous processes are those involving, for example, sheet extrusion or blow molding
machines.
Batch processes, for example, include injection molding machines.
The IP only evaluates this bit if main control byte 1, bit 2 = 1, or with selfĆtuning controllers.
In these cases 3Ćstep controllers operate with temporary IP internal controller parameter
modifications matched to the different machine types described above. In this way, 3Ćstep
controllers react ideally to the different temperature disturbances occurring with the different
machine types. The IP has therefore an optimized disturbance response.
If bits 4 to 7 are transferred to the IP with FB 162, the commands KS, PA or AE
(message 15) must be used.
