2.1 Pin numbering of the multipin plug
The pin numbering of the multipin plug (25-pin Sub-D plug) on
the valve terminal is shown in the diagram below.
(Pin 1 corresponds to address 0, ... Pin 22 corresponds to
address 21)
Recommendation:
In order to connect the type 12 valve terminal, use Festo
multipin sockets and multipin cables. Only then can you comply
with protection class IP 65.

Controlling the valve terminal
Always control the valve terminal in a uniform mode. Preferably
with all control signals positive-switching (1-switching) or all
control signals negative-switching (0-switching). Control in
mixed mode is not permitted.
