ABB Safety PLC

The ABB Pluto 2TLA series safety controller is an 'all-master' safety PLC device. This simplifies safety systems for its consumers and achieves the highest safety category of 4, according to EN 954-1. All Pluto’s are master units and can see the other Pluto’s inputs, outputs, and global memories. This enables the Pluto to evaluate the information from the other Pluto's and take appropriate decisions concerning its own safety devices. The gateway units are available for several different bus systems. Most of the modules in this family have dual safety outputs, potential free or PNP types. Up to 32 Pluto units can be safely connected in a 2-wire bus system to communicate with a superior system via a gateway or HMI displays. Therefore, within a maximum extended system 1472, I/O's can be connected. Also, all input components may be connected in series for even more complexity and optimisation.

The IDFIX is an identification circuit that allows multiple Pluto’s to be identified when connected on a bus system. This module is available to distribute a Tina adapter such as can be used to connect external safety monitoring equipment.

The IDFIX device is connected between the input terminals ID and 0V (also note that the IDFIX device is not required when using a single Pluto, however, the absence of an IDFIX requires to be stated when programming the Pluto device).
