Example 3 - Block Transfers
In this example, the module is set up in Class 1, Mode 3 using two
counters. This example uses indirect addressing and block transfers
with a PLC-5 scanner.
Three rungs are added to ladder file 8, the HSCE2 routine:
1. Repeating block transfer writes (BTW) to send eight words of
data to the remote 1746-HSCE2 module.
2. Repeating block transfer reads (BTR) to read eight words of data
from the remote 1746-HSCE2 module.
3. A rung to latch the first BTR done bit when it was satisfactory to
start the 1746-HSCE2 initialization (ladder file 9).
The 1746-HSCE2 initialization routine (ladder file 9) is nearly the same
as the local examples (examples 1 and 2), except the I/O image
