I converted a MICREX-F program to a MICREX-SX using StandardV3 loader. Contact and coil M8720 (TEMP0) which did not exist before conversion were created. Why?

Answer

The execution order of the contacts and coils in a ladder circuit partly differs between MICREX-F and MICREX-SX. Therefore, if a MICREX-F program is converted as it is, the operation may be changed.
In such a case, the circuit is divided during conversion in order to maintain the same operation. M8720 (TEMP0) and M8740 (TEMP1) are temporary memories used for data exchange between the divided circuits.
Multiple write of a coil causes no problem for the operation.
