Basic Information
Proposal of a new "management and setting" method for sensors
Features
Control and settings can be carried out remotely
Setting and checking incident light intensity for digital sensors FX-501(P), FX-502(P), FX-301(P)/305(P),
LS-501(P)/403., DPS-401(P)/402(P) and analog input unit SC-A01/A02, SC-T1JA that are scattered inside and outside equipment can be carried out remotely for all sensors by using the SC-GU1-485, which greatly improves ease of operations such as monitoring equipment that is running and also equipment starting and maintenance.
Note:
Used when the output signal is sent via a SC-GU1-485 to the PLC.
If the output signal is sent directly to the PLC, a quick-connection cable(sub cable) (CN-72-C□, CN-71-C□) should be used.
High general applicability so that any type of PLC can be used
RS-485 communication provides a high level of general compatibility so that any type of PLC can be used.
Integration with existing systems is possible without the need to change PLCs.
Features
* The maximum number of units is 12 for configurations including either the FX-501(P)/502(P) or LS-501(P).
- Control and settings can be carried out remotely
- High general applicability so that any type of PLC can be used
- Communication speed 57.6 kbps Series connection of a maximum of 31 nodes is possible
- Up to 16 digital sensors* can be connected side by side
- Save wiring, construction and space
Applications
Centralized control and setting of scattered digital sensors (FX-301/305) is possible using a PLC or personal computer.
Order guide
System configuration
Notes:1) The maximum number of units is 12 for configurations including either theFX-501(P)/502(P)orLS-501(P).2) Used when the output signal is sent via aSC-GU1-485to the PLC.3) Use when wiring output signal lines directly to a PLC. For more information on quick-connection cables, refer tothe instruction manualor this page on the digital sensors used in your environment such as forFX-501(P)/502(P).
