Automatically 2 zones are inserted to realize a memory that can be set and reset. The setting and resetting take place in each case with the operands 'S'. With the operands 'I' the memory can be queried. This is possible for the normal zone (query on logical 1) as well as for the inverted zone (query on logical 0).

Operands of the zone mem

If a zone mem is to be monitored in the step, it is necessary to enter the operand 'I'. The operands 'S' are used to wait for a change of state from logical 0 to logical 1 or to set or reset the memory. The Zone-Mem is used to remember process states.
