XP8300/XP8400/SE1100 Advanced Programming s 91
Sample Program for BL1000 and BL1300
The program locates all XP8300 and XP8400 boards attached to the
PLCBus. The program then loops, activating the relays on each board.
For each board, the program concludes with an all-on/all-off sequence. To
locate boards, the program polls all 64 possible addresses. The integer
(logical) address of each board that responds is displayed in Dynamic Cs
STDIO window.
