Tables 12–14 refer to double solenoid valves. With a single solenoid valve, only solenoid 14 is
used (bits 0, 2, 4, and 6).
Process data (output data for controlling the coils) of the modules on the valve side is stored in
Standardized Profile Area object (from object 0x6000) (corresponds to digital outputs,
object 0x6200) as well as in the Manufacturer-specific Profile Area (from object 0x2000).
Digital data is stored in 8-bit data types (UNSIGNED8). Analog data is stored in 16-bit data types
(INTEGER16).

Diagnostic data

The valve driver sends the diagnostic message as emergency telegrams to the bus coupler. It shows
the number of the module where the error occurred. The diagnostic message consists of
a diagnostic bit, which is set in the event of a short circuit of an output (group diagnostics).
The diagnostic bit can be read as follows:
Bit = 1: An error has occurred.
Bit = 0: No error has occurred.
6.3

Parameter data

The valve driver board does not contain any parameters.
The status and parameter data of the modules on the valve side is stored in the
Manufacturer-Specific Profile Area object (from object 0x2000). Modules on the valve side do not
have the parameter "Polarity."
