Examples:
STATIONMONITOR,2,3,4
Activates station disturbance word handling with reset feature on bus 2 via diagnostic triple at 3 with service address 4.
The normal address for the disturbance word is to be defined in the STATION directive.
STATIONMONITOR,1
Activates station without reset feature. The normal address for the disturbance word is to be defined in the STATION
directive.
Remark:
The service address is usually at
 4 for systems planned with Progress
 10 (HEX) for systems planned with EDS-P3
For each station to be monitored, a corresponding STATION instruction must be present.
STATION,<Bus>,<Station>,[<SA>],[<NA>]
Where:
Bus: 
Station: Station (Hex)
SA: Service address for disturbance word reset (Hex),
default from STATIONMONITOR instruction.
NA: Address of copy of station disturbance word in normal area (Hex), default from STATIONMONITOR
instruction.
Example:
STATION,2,1A,,F5
STATION,2,1B,,8E
STATION,2,1C,,ED
On bus 2, the stations 1A, 1B and 1C will be monitored. The normal addresses for the disturbance word are F5, 8E, ED
respectively. If the reset feature is active is determined by the STATIONMONITORING instruction.
Remarks:
 Resets are sent cyclically with the cycle CYC. Reset requests are only sent, if the station disturbance word (NA
copy) is not zero or if it is invalid respectively not available.
 Station disturbance word handling is only available via PIF connection.
 Be careful to define diagnostic triple, service address correctly according to the configuration in the
Procontrol P13 plant to avoid disturbances.
 The service address (SA) is usually at
o 4 for systems planned with Progress
o 10 (HEX) for systems planned with EDS-P3
3.3.3.4.11 LIMHYST Instruction
The LIMHIST instruction defines the hysteresis value for analog limit monitoring.
The hysteresis value has to be given as positive integer per mille value. The per mille value is from the display range or,
if this is zero, from the measuring range.
Example:
LIMHYST, 20
Defines a limit hysteresis of 20 %o
If no LIMHYST instruction is given, the limit hysteresis is set to 10%o (= 1%).
