4 (Holding Registers)
GP-Pro EX
0 (Coil), 1 (Discrete Input), 3 (Input Registers), 4 (Holding Registers)
● Address Formats
●Address formats are different between P-PRO/PB3 and GP-Pro EX
*
GP-PRO/PB3 supports only Modicon for a address format. With GP-Pro EX, the address format can be changed in "Individual Device Settings". You can select a address format from Modicon, IEC61131 (0 based), and IEC61131 (1 based).
