3-2-10 Slave Status 2
*_Slav2Sta (Slave Status 2) is used to reference 2 types of information: Master Node Address and
Slave I/O Allocation Status.
Use *_MstrNdAdrSta (Node Address of The Remote Master for Slave Communications) and
*_SlavIOAlocSta (Slave I/O Allocation Status) to reference individual information.
z *_MstrNdAdrSta (Node Address of The Remote Master for Slave
Communications)
This indicates the node address of the remote master for slave communications.
This information is valid when *_Slav1IO2CommSta (Remote I/O Communications for OUT 2/IN 2)
and *_Slav1IO1CommSta (Remote I/O Communications for OUT 1/IN 1) are TRUE in Slave Status
1.
z *_SlavIOAlocSta (Slave I/O Allocation Status)
This indicates the I/O allocation status of the slave.
