Appendix 1 Differences From the AJ71PB96
Following is an explanation between the AJ71PB96F/A1SJ71PB96F and the AJ71PB96.
(1) Number of communications
(a) AJ71PB96
If all of the PDU sizes for all of the communications are 200 or less; 32 communications.
Otherwise, 16 communications.
(b) AJ71PB96F/A1SJ71PB96F (refer to Section 4.3)
32 communications when the following conditions are met. Otherwise, 16 communications.
(b.1) Communication type conditions
Communications are divided into the following two categories.
•
Category I
MMAC, MSAC, MSAC_SI, FMA7 communications
•
Category II
MSCY, MSCY_SI, BRCT, MULT
The number of communications must satisfy the following formula.
Category I number of communications
×
2 + Category II number of communications
≤
32
(b.2) PDU size conditions
All of the PDU sizes for all of the communications are 200 or less.
(2) Remote OD management
(a) AJ71PB96
The total number of communications for the preload remote OD is 100.
The automatic remote OD is not on the connection units, but has a total of 1024 connections.
(b) AJ71PB96F/A1SJ71PB96F (refer to Section 4.5.3)
The remote ODs are managed by each communication and they are a maximum of 26 per
communication (total for automatic remote ODs and preload remote ODs).
There is a maximum of 20 preload ODs per communication.
Automatic remote ODs use the vacant area of the preload remote ODs.
(3) Station mode
(a) AJ71PB96
Operated as a master station or slave station.
(b) AJ71PB96F/A1SJ71PB96F
Operated as a master station. Has a slave emulation function for use as a slave station.
(4) Setting the station address and baud rate
(a) AJ71PB96
Set with the switch on the module.
(b) AJ71PB96F/A1SJ71PB96F
Set with SW0IX-PROFPE.
(5) The domain control, PI control, PutOD, FMA7 service
(a) AJ71PB96
Does not have these functions.
(b) AJ71PB96F/A1SJ71PB96F
Has these functions.
