1.2.3 COMMUNICATIONS ARCHITECTURE
A dedicated serial port is used for communication between the main processor and the human-machine interface. The
serial connection provides great immunity against electromagnetic disturbances, thus increasing system safety.
All 650 units incorporate an RS232 (USB or DB9) serial port on the front of the relay. There is also a possibility to
incorporate up to two additional communication modules on the rear.
One of the modules provides asynchronous serial communications, using different physical media (RS485 + cable remote
CAN bus I/O, plastic or glass fiber optic) depending on the selected model. The module incorporates two identical ports,
COM1 and COM2. The COM2 port is multiplexed with the front port. Additionally, this module may incorporate a port for
CAN BUS communications, used for the connection to the Remote CAN BUS I/O module. This feature allows increasing up
to 100% the I/O capability, when the maximum number of I/Os available inside the relay is not enough for a specific
application. Available options are:
Table 1–1: REAR SERIAL COMMUNICATIONS BOARD 1
The other module provides Ethernet communications (ETH Port), using 10/100BaseTX (self-negotiable speed) or
100BaseFX connectors, depending on the selected model. The most complete models include a double redundant
100BaseFX fiber optic port. Redundancy is provided at the physical level, for options D and E; the unit incorporates
internally duplicated and independent controllers for extended system reliability and accessibility.
Available Options are:
Table 1–2: REAR ETHERNET COMMUNICATIONS BOARD 2
For options C and D it is required to select the active physical media, by means of an internal selector inside the
module.The factory configuration for this selection is the 10/100BaseTX port. Starting from the version 7.00 the following
options are available.
Finally, internal communication with input and output modules is performed via an internal CAN bus, independent from the
one used for remote CAN BUS I/Os. This fact provides increased communication speed, as well as the possibility of
acknowledgement of modules, abnormalities, etc. As this is a serial port supporting a communications protocol, it provides
extraordinary immunity against external or internal disturbances.
