POINT
(1) Designate the number of device points within the following range:
(a)
When accessing the Q/LCPU on the station where the C24/E71 is loaded
(local station), or the Q/LCPU on the station connected on a Q/L series
supporting network system (CC-Link IE Controller Network, CC-Link IE
Field Network, MELSECNET/H, MELSECNET/10, or Ethernet) (other
station)
Number of device points
1)
Via the E71
2)
Via the C24
(b)
When accessing the QnACPU (other station), or the QCPU/QnACPU on
the station connected on a QnA series supporting network system
(MELSECNET/10, or Ethernet) (other station)
Number of device points
1)
Via the E71
2)
Via the C24
(c)
When accessing a programmable controller CPU other than the above
(other station)
Number of device points
