The elements can be written by the PLC of 0# station and directly read by other stations (1#--31#). 2) In mode 2, the M elements distributed to the sending area by 0# station range from M1400 to M1431. The elements can be written by the PLC of 0# station and directly read by other stations (1#--31#). IVC Series Small PLC Programming Manual
