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
