(2) Data register (D) details
(a) Effective cam No. register (D1241+10n) ....... Data sent from PCPU to SCPU
1) The No. of the cam currently being controlled is stored in binary code at
the effective cam No. register.
Cam No. updates occur at the sequence program's END processing.
2) The cam No. stored at the effective cam No. register is saved until
operation at another cam is executed. (A stored cam No. is not cleared
when control at that cam is ended.)
(b) Effective stroke register (D1242+10n, D1243+10n)
....................................................................... Data sent from PCPU to SCPU
1) The current control stroke is stored in binary code at this register.
(c) Current value in 1 cam shaft revolution register (D1244+10n, D1245+10n)
....................................................................... Data sent from PCPU to SCPU
1) The current value in 1 cam shaft revolution designated by the parameter
setting is stored at this register.
The current value is a ring address in the range "0 to [number of
PULSES per cam shaft revolution (Nc)−1]".
