8.2 RS-485 communications module
When looking onto the controller front, the connection for the optional
communication module is located on the left side in the controller housing (RJ-45
jack). A constant bus connection is required (data cable) to operate the
controller together with the RS-485 communcation module (8812-2002). The bus
line links the control units/devices in an open ring. At the end of the bus line, the
data cable is connected to the control station using a RS-485/RS-232 converter
(e.g. CoRe01, refer to Data Sheet T 5409 EN).
The maximum range of the bus connection (cable length) is 1,200 meters. A
maximum of 126 devices can be connected to such a segment. For greater
distances or when more than 126 devices are to be connected to a line, repeaters
(e.g. CoRe01) must be used to regenerate the level. A maximum of 246 devices
with 8-bit addressing can be con- nected to a bus.
If no communication is established between the control system and controller, the
time of any access by the control system to dynamic process can be restricted by
the Control system monitoring function. The controller resets the monitoring
function, provided the valid Modbus requests are registered. However, in case of
an error, all level bits are initialized back to “autonomous” after 30 minutes have
elapsed.
NOTICE
You are required to follow the relevant standards and regulations concerning
lightning and surge protection on installation.
