Fig. 3.4 Accuracy of AJ65VBTCU-68ADIN
Conversion speed indicates time from channel changing to A/D conversion completion.
Conversion speed per channel of the AJ65VBTCU-68ADVN/ADIN is 1ms.
Due to the data link processing time of the CC-Link system, there is a transmission
delay until the A/D conversion value is read actually.
For the data link processing time, refer to the user's manual of the master module
used.
Example1) Ver. 1 remote device station (ver. 1 compatible slave station) setting
Data link processing time taken in the asynchronous mode when the
master module is the QJ61BT11 (normal value)
[Calculation expression]
SM+LS×1+remote device station processing time
SM : Scan time of master station sequence program
LS : Link scan time
Remote device station processing time: (Number of channels used+1 )
: Internal processing time of AJ65VBTCU-68ADVN/ADIN
Example2) Ver. 2 remote device station (ver. 2 compatible slave station) setting
Data link processing time taken in the asynchronous mode when the
master module is the QJ61BT11N (normal value)
[Calculation expression]
(a) In the case of the remote input (RX), remote register (RWw)
SM + LS × 1 × m + remote device station processing time
(b) In the case of the remote output (RY), remote register (RWr)
SM + LS × 1 × (m + 1) + remote device station processing time
SM : Scan time of master station sequence program
LS : Link scan time
m : Constant
Remote device station processing time: (Number of channels used + 1
1: Expanded cyclic setting is quadruple in this module, m = 7.
