A2.1 Description PCS 830.3/.1 handling
Settings of the board
adressing (6-segment DIL switch) The PCS board 830.3 is an interface module with three built-in TTY (20
mA) interfaces (active or passive). The PCS 830.1 is identical but it is
only equipped with 1 TTY interface (2 current sources).
It is used for the communication between a BOSCH programmable con-
trollers CL300, CL400, CL500 or PC600 and one (PCS 830.1) or three
(PCS 830.3) operating consoles. The PCS 830.3 and PCS 830.1 boards
are slot-independant. The PCS 830.3 uses altogether 12 additional input
bytes and additional output bytes (EZ/AZ). 4 EZ/AZ addresses are required
for each interface (channel). The PCS 830.1 requires exactly 4 EZ/AZ
addresses.
Each channel can be freely addressed in steps of 4 via one 6-segment
DIL-switch. Please take care that the set address does not intersect with
already used addresses or channels! Refer to section 2.1 (Specifications
of the PCS 830.3/1) for the position of the DIL-switch segments of the
corresponding channel.
Selection of the address
Among others, the areas EZ0 to EZ63 and AZ0 to AZ63 are reserved for
analog I/O boards. The PCS 830.3/31 board is also addressed in this
area. The base address can be set to 0 and to all addresses divisible by
4. Input and output addresses (EZ/AZ) must lie in parallel, i.e. they can
not be differently set.
Attention!
Take note, that after re-addressing of the board you must adjust the first
three words of the cross-reference data.
