
J4 & J5: Printer/Debug / Host Computer
Two connectors for 10-pole flat cable, allowing the connection of a 40 or 80 column serial printer
and of a PC for configuration data transfer. Use the S81-CFT10/2 cable for connecting to the PC.
 J6: Display
A connector for 20-pole flat cable, allowing the connection to the S81-U1006 display module.

Description
This module is system central unit. Besides the micro-controller, the module
includes the following elements: Flash memory, buffered static Ram, watchdog
circuit and Ethernet controller. The CPU module can be used in both single and
redundant configuration. In this last case, two CPUs operating in parallel are
used. Both CPUs process the information received from the modules, but only
one of the two CPUs runs the commands. In case of failure of the primary CPU,
the other one keeps on carrying out all the tasks without any interruption of the
machine cycle.
