Answer from slave to master:
Transmission of the process reflection
The slave sends the following parameter-values:
Byte 1 + 2:
status setpoint transmission:
the last instruction was OK.
Byte 3 + 4:
Zone 1
Act. process temp. value:55,0°C
550de c.=0x0226hex., 16 bit integer-value
Byte 5:
Zone 1
Controller status:
controller = on
Byte 6:
Zone 1
Alarm status:
alarm = no alarm
Byte 7 + 8:
Zone 2
Act. process temp. value:56,0°C
560de c.=0x0230hex, 16 bit integer-value
Byte 9:
Zone 2
Controller status:
controller = on
Byte 10:
Zone 2
Alarm status:
alarm = Alarm 2 active

If there are instruments with controller zones lower than 16 (e.g. 8 or 12 zones) the number of the
transmitted data bytes is lower too.
