Simpac - Model PMSS - Protection Terminal
From Operation & Engineering Consoles
The SIMPAC PMSS protection terminal is based on a powerful workstation computer that allocates all software necessary to monitor and control substation protection systems. Using a CIC™ (Intelligent Communications Controller or Front End Processor), information is acquired from the IEDs and then transmitted locally and/or remotely to the Protection Terminal. Local access is done typically using a LAN Ethernet.

Products Details
The SIMPAC CIC’s communication capabilities allow for remote reliable access through WAN, radio or other available means, it is loaded with software to access Protection Relays. 4 ways of accessing are available:
- SCADA
- Through Port / OEM proprietary software
- EXPOPAC™ Software
- SAMPAC Optional
SCADA:
The SCADA functions on this terminal allow acquiring and managing all Real Time information that comes from the substation.
THROUGH PORT / OEM
PROPRIETARY SOFTWARE
The Through Port function allows the user to access the protection Relay as if connecting directly with a Laptop.
EXPOPAC
The EXPOPAC software presents all the information available from any IED in the same format.
SAMPAC
SAMPAC is a Maintenance module developed by SEPAC to manage transformers and breakers. This application comes as an option but it can be very useful in predictive and preventive maintenance. Protection Terminal

The system can also be connected using RS- 485 links or by fiber optics. In this architecture, the CIC becomes the heart of the system. It has the capability of managing up to 32 independent channels. Each channel can handle a different communications protocol, thus making it possible to access different brands of Protection Relays. Another option for the basic architecture is building different communication networks. Each Network has a different communication protocol and IEDs with the same protocol can be connected on the same network. The CIC is also capable of accepting legacy RTUs if necessary in order to acquire digital I/O information for monitoring functions.

- RS 232
- Legacy RTU
- RS 485
- IEEE 802.3
Depending on the IEDs individual connectivity capabilities, equipment from the same OEM can be in a single network or on different networks to optimize response time. Depending on the user’s specification, either array is possible. The system’s flexibility is an advantage for the user, for he can choose the most convenient way of connecting the devices.
