The WRITE_PCMCIA function transfers data from the PLC's RAM memory to the user memory card archiving zone. The function WRITE_U_PCMCIA enables to address the PLC zone's beginning to be copied to the PCMCIA card up to 65 535 (instead of 32 767 for WRITE_PCMCIA function) and is therefore recommended to be used instead of WRITE_PCMCIA function.
The additional parameters and can be configured.
