Table 1: Bit Memory Map Profile of VAT CC-Link slave
m: Address assigned to the master module by the station number setting. This means that the address
range for this slave begins at address m of the master.
n: Dependent on the VAT Operational settings mode (number of occupied stations and number of
extension cycles)
Operational settings mode = 1
n = 0x7 (hex)
Operational settings mode = 4
n = 0xD (hex)
Example see chapter: 4.8.3 Example of the handshaking by a PLC-program.
