Outputting Error Signals - Panasonic S-LINK V User Manual

● The main line is the longest route distributed from the controller or control board.
NOTE
● The branch lines are the routes branched from the main line.
The total cable length should satisfy the conditions shown in the following table:
The maximum transmission distance (between D and G) is as follows:
● Mode A: 50m
The maximum length is 50m regardless of the cable conductor cross section (0.3 to 2.0mm
of nodes (1 to 256 nodes).

age drop value, and use a local power supply unit, etc. to prevent voltage drop.
For a detailed description, refer to page 23.
● The conductor cross section of the exclusive 4-core flat cable SL-RCM□ is 0.5mm
● Wire the S-LINK V system while observing the communication distance specifications de-
scribed above. In addition, use the cables that satisfy the specifications described above.
● To select applicable cables, refer to the section describing cables.
For a detailed description, refer to page 153.
● The picking switch SL-VPK0□ cannot be used in mode A (transmission mode).

Outputting Error Signals

If the controller is equipped with the error signal output function, the controller can output an error signal after
detection of an error.
To output an error signal, the S-LINK V system will be turned on properly. If an error occurs, the NPN output
transistor will be turned off.
For each type of error, you can select whether the error signal should be output.
For the Troubleshooting, refer to page 166.
For the error, refer to page 170.
