Safety remote mixed I/O modules XPSMF3
Safety PLCs
In order to meet safety requirements, the safety remote mixed I/O modules
XPSMF3pIOppppp incorporate two essential functions (Redundancy and
Self-monitoring) complying to category 4 conforming to EN 954-1 and performance
level “e” conforming to EN/ISO 13849-1 in addition to the SafeEthernet safety
communication protocol between these safety remote mixed I/O modules and the
safety PLCs (Special Switch).
bb Redundancy: the dual processor integrated in safety modules
XPSMF3pIOppppp analyzes and compares the data received from the safety inputs
and outputs. The incoming and outgoing data (programmed values and received
values) are received in parallel by the two processors and compared in real-time.
bb Self-monitoring (“Watchdog”): the safety remote mixed I/O modules
XPSMF3pIOppppp continuously monitor the data processing cycle and the
execution of tasks, and intervenes if the cycle time does not conform to the
predefined value.
bb The integrated switch (Special Switch) stores for a very short time and sends at
very high speed the data provided by the inputs and outputs of the safety modules on
the Ethernet network, while avoiding signal collisions and excessive amounts of data
on the network.
