NTRATE, VARSHI, VARSHO

The NTID command establishes the Network Unit ID for a 6K unit involved in a peer-to-peer Ethernet connection with other 6K or Gem6K products. Up to eight 6K or Gem6K products may be connected in the peer-to-peer network.

Saved in Non-Volatile Memory

This command is saved in the controller’s non-volatile memory, and is remembered on power-up and RESET.

Implementation process for peer-to-peer communication (further details are provided in the Programmer’s Guide):

1.Connect the 6K/Gem6K products to the network and configure each 6K/Gem6K for Ethernet communication according to the Ethernet Networking configuration procedures in the Programmer’s Guide.

2.Set the broadcasting rate with NTRATE command, preferably the same rate (50 milliseconds is recommended) for each unit.

3.If the unit is to receive data only (not send) you are finished with the setup for that unit. If the unit is to also send, complete steps 4 and 5.

4.Assign a unique unit number (1-8) with the NTID command.

5.Assign data to the broadcast variables (up to eight) with the VARSHO command.

6.Repeat steps 2-5 for each unit in the peer-to-peer network.

Example:

;

Unit #2 will broadcast at 50-millisecond intervals

;*************************************************************************************

;*************************************************************************************

;CONNECT TO 6K UNIT #3 AND SEND THE FOLLOWING SETUP COMMANDS

NTRATE50

; Unit #3 will broadcast at 50-millisecond intervals

;This third unit will receive data only. Therefore, it does

;not require a unit ID number or VARSHO data assignment.
