PC Master TCP/IP Slave Communications

 

Overview

The PC Master (PCM) software is a program that is designed to allow a PC to perform the polling and communications duties normally handled by the Master panel.  A computer running the PCM software will take the place of the Master panel.  This arrangement provides three advantages:

 

1.                  Communications to the Slave panels can be routed through a serial port or through the TCP/IP network.

 

2.                  Greater control can be exerted over the Master to Slave polling frequency. This will allow the system to function over slower communications methods.

 

3.                  The communications to the Slave panels can be separated into several different channels that operate simultaneously.  This can provide a substantial increase in the rate of data collection and data distribution.

 

Requirements

1.                  The PCM software is purchased separately from the WinDSX software.

 

2.                  It is installed on a PC that conforms to the PC Requirements of WinDSX.

 

3.                  The Workstation running PCM, the Comm Server and all LAN serial devices must have a static TCP/IP address.

 

Operation

The Comm Server communicates to the PCM computer over the network. It downloads the Location data to the PCM and supervises the communication to the PCM just as if it were a Master Controller. The PCM then communicates and Polls the Slave panels just like a Master Controller. The only difference is the Slave controllers are connected to the Network using LAN Serial Devices such as the one manufactured by DSX. The PCM can communicate with up to 63 Slave controllers each with its own LAN connection or multiple Slave Controllers can be connected to the same LAN serial device. The PCM supervises the communication to these LAN connected Slave panels and performs all global communication duties such as Linking and Anti-Passback.

 

Each PCM represents 1 Location. Multiple PCM computers can be used to allow the Comm Server to communicate with more than 1 Location via the

LAN/WAN.
