Metasys Slave Port Functionality 2 1500-RPK ♦ Raypak Burner Controller Metasys Slave Port Functionality In This Chapter 2.1 ¾ N2 Slave Communications ....................................................... 7 ¾ N2 Point Layout........................................................................ 9 N2 Slave Communications The ProSoft 1500 card supports the Johnson Controls Metasys™ N2 Protocol, as a slave, on port 1.
1500-RPK ♦ Raypak Burner Controller Metasys Slave Port Functionality Data Types The N2 System protocol treats data as objects, with each data type having a different structure and purpose. The data types recognized by the 1500 card are as follows: Binary Input Binary Output Analog Input Analog Output Reading Attributes The data objects contain attributes which describe several a data point, and some of its functionality.
Metasys Slave Port Functionality 1500-RPK ♦ Raypak Burner Controller Status Update The host can issue a 'Status Update' command to the 1500. The response will contain device information ("1500-N2 Rev 1.0A") as well as current status information. 0/9 Status Update Identify Device When a master host first powers up, the 'Identify Device' command is issued to all of the slaves. In the case of the 1500 card, the Device Code 10 Hex is returned to the host.

Hardware Setup 3.2 1500-RPK ♦ Raypak Burner Controller B6000 Communications The B6000 communications interface has been hard coded to operate at the following default conditions: Baud 9600 Parity Odd Stop Bits 1 The 1500 card emulates the modem card that is regularly connected to the B6000 Controller. This is important as when the 1500 card is connected to the B6000, the modem card cannot be connected simultaneously. Default Baud Rates and Parity for all supported devices are different.
