D0 to D8 stores the following as a protocol setting data.
In this program example, a receiving side program is not required.
(0) When 'bStart' (M0) is turned on, the protocol is executed by the GP.ECPRTCL instruction and D100 to D109 of the receiving side CPU module is read

D4 Monitoring timer 10H The monitoring timer is set to 4 seconds. (Unit: 250ms)
D5 to D6 Head device No. 100 To read D100 to D109, start device number is set to 100.
D7 Device code A8H To read D100 to D109, device code is set to A8H.
D8 Number of device points 10 To read 10 points from D100 to D109, number of device points is set to 10.
