Safety PLCs
There are no restrictions in terms of sending information to an external PLC or HMI
terminal, regardless of the type of Ethernet or Modbus Plus network used or the
particular protocol involved. By contrast, data can only be received (written to the
Safety PLC) in the “unrestricted” memory area
The Quantum Safety PLC is capable of communicating with other PLCs via:
b
b
b
These communication methods are classed as “non-interfering”.
The Ethernet network connects:
b
b
Note: With a Hot Standby Safety CPU, the Ethernet port is reserved for data exchange between
Ethernet module 140 NOE 771 11 has been certified as a non-interfering product for
use with a Quantum Safety PLC.
Both peer-to-peer and Global Data communication are supported. Standard
Ethernet components can be used for the wiring.
Using Unity Pro
and write directions in the Ethernet network configuration. Unity Pro XLS checks that
read data is only using (being written to) the “un restricted” memory area
Global Data communication is configured within the Ethernet network configuration
in Unity Pro XLS so that write data can be published and read data can be
subscribed to.
Read data may only be sent to the “un restricted” memory area
On a Modbus Plus network, the CPU's Modbus Plus port is used for peer-to-peer
communication and Global Data exchange.
Using Unity Pro XLS, this type of communication is defined separately for the read
and write directions in the Modbus Plus network configuration. Unity Pro XLS checks
that read data is only using (being written to) the “un restricted” memory area
Global Data communication is defined within the Modbus Plus network configuration
in Unity Pro XLS so that write data can be published and read data can be
subscribed to.
Read data may only be sent to the “un restricted” memory area
