8.2.1.2. Description of the standard parameters
These parameters are included in the physical block, in the function block and in the transducer block.
Parameter Description
ALARM_SUM
This parameter includes the current status of the block alarm. The parameter
ALARM_SUM is not yet supported.
ALERT_KEY
This parameter includes the identification number of the plant unit. As a result, the
location (plant unit) of an event can be detected.
MODE_BLK
This parameter includes the current mode and the permitted and normal mode of the
block.
ST_REV
A module has static parameters which are not changed by the process. Values are
assigned to these parameters during the configuration or optimisation. The values
of the parameters ST_REV must increase by 1 whenever a static block parameter is
changed. As a result, the parameter revision can be checked.
STRATEGY
Arrangement of the function module. The STRATEGY field can be used to group
blocks.
TAG_DESC
Each block can be assigned a written TAG description. TAG_DESC is the address
of the block. TAG_DESC must be unique and standard in the field bus system.
TARGET_MODE
The TARGET_MODUS includes the required mode which is usually specified by a
control application or by operating personnel.

Out of service (O/S)
The block was not specified. If the initial value was specified during a certain failsafe value, the last value or the configured fail-safe value is retained.
Manual l (Man)
The output block is specified directly by the user by means of an interface
command.
Automatic (Auto)
The Invert parameter is used to form the output value.
Remote Cascade
(RCas)
The set-point block was set by a control application which works on an interface
device via the remote cascade parameter RCAS_IN.
The version of a function block or transducer block is checked by the mode parameter. Values of the subindex
mode are defined as follows:
1. Target
This is the mode which is requested by the user. The values which are authorized by parameters of the permitted
mode, are limited for target. The modes are specified by the bit string in the following manner:
Bit Mode
7
Out of service (O/S) - MSB
4
Manual (Man)
3
Automatic (Auto)
1
Remote - Cascade (RCas)
The “automatic” modes which are used in this profile are Auto and RCas; manual mode: Man. In the O/S mode
the normal algorithm is not implemented and each pending alarm is deleted.
2. Current
This is the present mode of the module which may differ from the target mode which is based on operating
conditions.

SP_D
Set-point value
Bit 0 in the value specifies the valve position. The transferred status must be a
“good” status, e.g. 0x80.
OUT_D
Process value of the valve position. Bit 0 in the value indicates the valve position.
RCAS_IN_D
Set-point value in the RCAS status (Remote Cascade). Bit 0 in the value specifies
the valve position. The transferred status must be a “good” status, e.g. 0x80.
RCAS_OUT_D
Process value of the valve position in the RCAS status. Bit 0 in the value indicates
the valve position.
CHANNEL
Indicates the transducer block. There are channels 1-4. The function blocks are permanently assigned.
INVERT
Inverts the set-point value in the AUTO or RCAS status0 = do not invert1 = invert
FSAVE_TIME
Time in seconds after which the “Failsave” action starts following a break in the
cyclic communication. The maximum value for this time is approx. 18 hours.
FSAVE_TYP
Response to “Fail save”
0 = Valve retains the last status
1 = Valve switches according to FSAVE_VAL_D
2 = Isolate valve
FSAVE-VAL-D
Valve position in “Fail save”, if selected.
SIMULATE
Allows the simulation of READBACK_D

Malfunctions
9 MALFUNCTIONS
Malfunction Possible cause Remedial action
Valves do not switch: No or inadequate oper-
ating voltage.
→ Check the electrical connection.
→ Ensure the operating voltage according to type plate.
Inadequate or no
pressure supply.
→ Design the pressure supply with the largest possible
volume (even for upstream devices such as pressure
controllers, maintenance units, shut-off valves, etc.).
Minimum operating pressure ≥ 2.5 bar
Valves switch with a
delay or blow off at the
deaeration connections:
Inadequate or no
pressure supply.
→ Design the pressure supply with the largest possible
volume (even for upstream devices such as pressure
controllers, maintenance units, shut-off valves, etc.).
Minimum operating pressure ≥ 2.5 bar
Deaeration of the
exhaust air ducts inadequate due to too small
or dirty silencers (back
pressures).
→ Use appropriately sized silencers or expansion tanks.
→ Clean dirty silencers.
Impurities or foreign
objects in the pilot valve
or main valve.
→ Apply pulsed pressure to the exhaust air ducts to blow
out the impurities; install a new pilot valve or main
valve if this procedure is unsuccessful.
