Perform preset memory content settings using key operations on the device or using IO-Link communication parameters.
*3: Set this bit to 1 (True) if using IO-Link communication control. Control will not execute if set to 0 (False).
Note the following wh en using flow contro l/forced OFF via device key input.
Note: The "start/stop" bit of Process Data OUT has the same role as "Flow control/Forced OFF" status switched by key operation.
However, when the "start/stop" bit is "1 (Start)", if th e flow control is fo rcibly turned OFF via key input from the device, the "start/stop" bit of Process
Data IN will be "0 (Stop)" and the product will be in the forced OFF, but the "start/stop" bit of Process Data OUT will remain as "1 (Start)". Therefore,
always check the "start/stop" status of the device using the "start/stop" bit of Process Data IN.
Also, when switching the " start (flow control) " state from the master in this state, set it to "0 (stop)" and then set it to "1 (start)" again.
Refer to the SM-A19060 instruction manual for usage methods.
000F 423F (hex) ⇒ 999999 (dec)
For FCM-0005*-*C, Table 1 on P14 shows the integrating flow as 99999.9 L.
