(d) SB/SW signals used with the CC-Link IE Field Network synchronous communication
function
To check the operating status of the D/A converter module (synchronous or asynchronous), use the following
link special register (SW) on the master station.
• Synchronous/asynchronous operation status information (each station) (SW01C8 to SW01CF)
For details, refer to the following:
When the master station is RJ71GF11-T2 or RJ71EN71
•
MELSEC iQ-R CC-Link IE Field Network User's Manual (Application)
When the master station is a simple motion module
•
MELSEC-Q QD77GF Simple Motion Module User's Manual (Network)
When writing a value to CH
Digital value (RWw2 to RWw5, RWw12 to RWw15), use the condition of the
above mentioned link special register (SW) (the corresponding bit of the register being on) as an interlock.
The following figure shows the program example to write a value to CH1 Digital value and CH2 Digital value of
the main D/A converter module with station number 17.
(4) Setting procedure (master station)
1.
Set the synchronization cycle of the master station to any of the following.
• 0.88ms
• 1.77ms
• 3.55ms
For details on the setting method, refer to the following:
When the master station is RJ71GF11-T2 or RJ71EN71
