For a description of the diagnostic data for the valve zone, see section
g 6. Structure of the Valve Driver Data and g 7. Structure of the Elec-
trical Supply Plate Data. A description of the diagnostic data for AV-EP
pressure regulators can be found in the operating instructions for AV-
EP pressure regulators. The diagnostic data for the I/O zone is de-
scribed in the system descriptions of the individual I/O modules.
In CoE object 0x9000, the group diagnostic bits of max. 32 modules can be read
out in bytes 1–4 and the group diagnostic bits of max. 10 I/O modules can be
read out in bytes 5–6. Internal service data is displayed in bytes 7–7E.

5.7 Transferring the configuration to the controller

Data may be transferred to the controller once the system is completely and cor-
rectly configured.
1. Make sure that the controller parameter settings are compatible with those of
the valve system.
2. Establish a connection to the controller.
3. Transfer the valve system data to the controller. The precise process depends
on the PLC configuration program. Observe the respective documentation.

6 Structure of the Valve Driver Data

6.1 Process data

Incorrect data assignment!
Danger caused by uncontrolled movement of the system.
Always set the unused bits to the value "0".
u
The valve driver board receives output data from the controller with set points for
the position of the valve solenoid coils. The valve driver translates this data into
the voltage required to actuate the valves. The length of the output data is eight
bits. Of these, 4 bits are used with a 2x valve driver board, 6 bits with a 3x valve
driver board, and 8 bits with a 4x valve driver board.
The following figure shows how valve positions are assigned on 2x, 3x, and 4x
valve driver boards.

Bits that are marked with a "–" may not be used and are assigned the value "0".
These tables refer to double solenoid valves, see g Table 8, g Table 9
and g Table 10. With a single solenoid valve, only solenoid 14 is used
(bits 0, 2, 4, and 6).

6.2 Diagnostic data

In CoE object 0x9000, the group diagnostic bits of max. 32 modules on the valve
side can be read out in bytes 1–4. The bit position corresponds to the number of
the module. The least significant bit (bit 0, byte 1) shows the group diagnostic
message of the first module to the right of the bus module. Bit 1, byte 1 shows
the group diagnostic bit of the 2nd module. Up to the highest bit (bit 7, byte 4),
which shows the group diagnostic bit for a possible 32nd module.

6.3 Parameter data

The valve driver board does not contain any parameters. The parameters of the
pressure regulators can be changed in the CoE object 8000, bytes 1-126, in PRE-
OPERATIONAL status.

7 Structure of the Electrical Supply Plate Data

The electrical supply plate interrupts the UA voltage coming from the left and
transfers the voltage supplied by the additional M12 plug to the right. All other
signals are directly passed on.
7.1 Process data
The electrical supply plate does not have any process data.
7.2 Diagnostic data
The electrical supply plate sends a manufacturer-specific diagnostic message to
20
the bus coupler, which indicates a missing actuator voltage (UA) or that the sys-
tem has fallen below the tolerance value of 21.6 V DC (24 V DC -10% = UA-ON).
The bus coupler transmits the group diagnostic bits of the first 6 modules (supply
modules and UA-OFF modules) in the sequence from left to right cyclically to the
control in the status PDO 0x1AFF in bits 11–16. Bit 24 "valve module side diag-
nostic bit" is set simultaneously. In addition, the group diagnostic bits, including
those of further supply modules, can be evaluated in the acyclic CoE object
0x9000.
