Chapter 3 - Control system
I/O module identification
Communication with AMC circuit board
Wiring
3-10 (14)
The I/O modules are identified in the drive and in the wiring diagrams by
their technical designation (eg, A2511). Additionally, a cluster-position
designation is used in the wiring diagrams and in the software. This
designation has no relevance to the connection of the control cables but
is used to help identify a device in the software and the
parameter table.
A cluster is a synonym for the group of S800 I/O modules of the control
system. Each I/O module belongs to a cluster (C) and occupies a fixed
position (P) within the cluster. The relation between cluster and position is
expressed by the designation CxPy, with x representing the number of the
cluster and y identifying the number of the position.
All I/O modules used in the drive belong to cluster 1 and each I/O module
occupies a fixed position between 1 and 10.
The fixed position is the reason why there can be empty MTUs in the
control compartment. Example: If interface package CI2 is not part of the
control compartment, the MTUs of CI2 are present.
The AMC circuit board communicates with the S800 I/O system via the TB
820 bus modem. A fast optical link connects the devices with each other.
The optical link uses the standard DDCS protocol. Data between the bus
modem and the I/O modules is transmitted through the S800 ModuleBus.
A section of the ModuleBus is contained in each MTU where the I/O
module is plugged into.
The external I/O signals of the standard S800 I/O station are connected to
separate terminals in the control compartment. The internal wiring
between terminals and I/O modules is made in the factory.
The wires to the optional S800 I/O station are connected to the module
terminal units.
