HV052 10. Installation I/O Terminal YS8 EtherNet/IP-Compliant User’s Manual Ver. 1.0 10. Installation This section describes how to install I/O terminals. 10-1. Installation via Direct Mounting Obtain M4 screws and screw them perpendicularly to the mounting holes. [Tightening torque 1.47 N ・ m ± 15%] 10-2.
・ When wiring with stranded wires, twist the wires so that there are no whiskers. ・ Do not solder the wire ends. ・ When removing the connectors from the modules, loosen the connector screws (except with YS8- D16N) and pull the connector straight out of the module.
HV052 12. I/O Data Allocation I/O Terminal YS8 EtherNet/IP-Compliant User’s Manual Ver. 1.0 12. I/O Data Allocation Performs fixed-size, fixed-address I/O data allocation regardless of the type or serial number of the valves connected to the communication module or the type or connection location of the I/O expansion module.
HV052 12. I/O Data Allocation I/O Terminal YS8 EtherNet/IP-Compliant User’s Manual Ver. 1.0 12-2. Relationship Between I/O Data Allocation and Solenoid Valves The relationship between the solenoid valves and the allocation of I/O data varies according to the "wiring specifications" specified in the order number of the manifold.
・ While YS8-D8N and YS8-D8N-P have 8-channel specifications, note that the I/O area uses 2 bytes (16 channels). The latter byte is a reserved area and cannot be used. ・ The YS8-A4N channels store the AD conversion value in the first 12 bits of the allocated 2-byte I/O area. The high-order 4 bits cannot be used.
The latter byte is a reserved area and cannot be used. ・ The YS8-A2S channels performs DA conversion of the value stored in the first 12 bits of the allocated 2-byte I/O area. The high-order 4 bits cannot be used.
I/O Terminal YS8 EtherNet/IP-Compliant User’s Manual Ver. 1.0 13. Parameter Settings YS8-M3 has parameters that can be set for each module/channel. The various parameters can be set using the support software provided by the PLC vendor or Explicit Message communication.

HV052 13. Parameter Settings I/O Terminal YS8 EtherNet/IP-Compliant User’s Manual Ver. 1.0 13-2-3. Analog Input Filter Measured Value Intended Uses When the input value fluctuates and is unstable due to noise and other factors, the input value is stabilized by taking a moving average.
HV052 14. Network Topology I/O Terminal YS8 EtherNet/IP-Compliant User’s Manual Ver. 1.0 14. Network Topology The YS8-M3 supports the following connection formats. ◦ Line format ◦ Star format ◦ Device level ring format 14-1. Line Format A line format network connects devices in a daisy chain format. Switching hubs are not needed, and the total length of the LAN cable can be reduced.
HV052 14. Network Topology I/O Terminal YS8 EtherNet/IP-Compliant User’s Manual Ver. 1.0 14-3. Device Level Ring Format A device level ring (hereafter DLR) format network is resilient to breakdowns. The connections are maintained by switching to line format communications if a line is cut or a device in the ring malfunctions. A control device known as a supervisor must be installed on the network.
