Festo 03 - Calculating the Configuration Data

Calculating the configuration data
Before configuring, calculate the exact number of
available inputs/outputs. A modular valve termi-
nal consists of a different number of I/Os,
depending on the type ordered.
PLEASE NOTE
•
The terminal makes available four
status bits for diagnosis via the field bus.
These are automatically assigned within
the terminal when there are input modules.
•
The status bits occupy four extra
input addresses.
The following table shows the I/Os per module
required for the configuration:
Module type Number of assigned I/Os *)
S valve sub-base (type 03)
D valve sub-base (type 03)
ISO sub-base (type 05)
- 4 valve locations
- 8 valve locations
- 12 valve locations
Output module (4 digital outputs)
Input module (4 digital inputs)
Input module (8 digital inputs)
Status bits **)
2 outputs
4 outputs
8 outputs
16 outputs
24 outputs

*) The I/Os are assigned automatically within the terminal,
irrespective of whether an input/output is actually used.
**) The status bits are assigned automatically within the terminal,
as soon as input modules are available.
