Initialization PLC
Recall that ACC-72EX requires a reset after each power up, power cycle, $$$ (reset), or $$$*** (factory
default reset). This can be achieved with a startup (or initialization) PLC. Example:
// ACC-72EX initialization PLC
/****************************************/
open plc Acc72EX_StartupPLC
local endtime;
disable plc 2..31 // Disable all other tasks
// Defining pointers for system channel mailboxes
