The sample program sb.c simply writes out blocks of data to a PLC-5/PLC-2 integer file over the Data Highway/Data Highway Plus using the administrator. It does not include network support for QNX 4; it must run on the node where the administrator is running.

Consider the consequences of writing to the PLC integer file before running this program. Writing to the data table of a running processor could result in erratic machine operation and damage to equipment and/or injury to personnel.
