Connection Of End Unit; Current Consumption - Panasonic SL-VGU1-EC User Manual

System Outline

Connection of End Unit

CAUTION
If the cable lengths are the same, connect the end unit to the line having fewer nodes.
Be sure to connect one SL-VEU end unit to the end of the main line.
If the branch line length exceeds 80% of the maximum transmission distance, connect one SL-VEU unit to the
end of the branch line, too.
<If the branch line length is equal to the main line length>
Same length (Note 1)
<If the branch line length is 80% of the main line length or more>
Maximum transmission distance
80% of main line length or more
Notes: 1) Even if the cable lengths are the same, if both the main and branch line lengths exceed 80% of the maximum
transmission distance, connect two SL-VEU end units. Note that it is not possible to connect more than two
SL-VEU end units.
2) The maximum transmission distance depends on the cable conductor cross section and the number of nodes.

Current Consumption

To determine the total current consumption, check the current consumption of each I/O unit.
Calculate the power supply capacity while referring to the list of current consumption values shown in the
'S-LINK V User's Manual.'
