Keep spare parts on hand: - Stock up on maintenance parts including spare modules, in advance. Discharge static electricity before operating the system: - Because static charge can accumulate in dry conditions, first touch grounded metal to discharge any static electricity before touching the system. Never use solvents such as paint thinner for cleaning: - Gently clean the surfaces of the FA-M3 controller with a cloth that has been soaked in water or a neutral detergent and wringed.

Overview The Yokogawa High-speed Link System (YHLS) master module F3LH02-0N has two YHLS master interface ports for connecting slave units to perform remote I/O. Table 1.1 Applicable Module Model Code Module Name F3LH02-0N YHLS Master Module What is YHLS? Yokogawa High-speed Link System (YHLS) is designed for implementing high-speed remote I/O in an FA-M3 system.
1.2.4 Constant Communication Cycle Time YHLS features a constant communication cycle time, not affected by automatic participation or withdrawal of slave units, thus delivering reliable communications with constant cycle time under all circumstances. 1.2.5 Control of YHLS Output States when CPU Stops If the sequence CPU module switches to STOP mode, the YHLS master module also stops communications with the slave units.
12 Mbps max., 2 YHLS ports Operating Environment There is no restriction on the type of CPU module that can be used with the F3LH02-0N module. The F3LH02-0N module may be installed in the main unit but not in a sub-unit.

CAT5 shielded cable or equivalent - Shielded twisted-pair cable - Impedance: 100 Ω - Conductor size: AWG24 CAUTION - If a different type of cable is recommended for a slave unit by its manufacturer, use that cable instead.
Attaching/Detaching the Module Attaching the Module Figure 2.2 shows how to attach this module to the base module. First hook the anchor slot at the bottom of the module to be attached onto the anchor pin on the bottom of the base module.

Attaching the Module in Intense Vibration Environments If the module is used in intense vibration environments, fasten the module with a screw. Use screws of type listed in the table below. Insert these screws into the screw holes on top of the module and tighten them with a Phillips screwdriver.
Functions This chapter describes the functions of the YHLS master module. List of Functions Table 3.1 List of Functions Functions Description Section: I/O communication with slave units for ON/OFF control and Communication with slave units monitoring.

Communication with Slave Units 3.2.1 Starting Communications After setting the transmission speed, communications mode and the slave unit last address for the YHLS master module, turn on the Request to Communicate relay start communication between YHLS master module and the slave units. 3.2.2 Input Input statuses of slave units are transmitted to the YHLS master module and stored in its...
Withdrawal of Slave Unit A slave unit that is no longer available for communication due to power off or any other reason is withdrawn from the network and communication continues with the remaining normal slave units. Error YHLS master module Slave Slave Slave...
Before using this function, you should set the output at CPU failure to ‘RESET’ in the DIO setup for the slot installed with the F3LH02-0N master module in the configuration setup of the CPU module. The output condition (reset or hold) of a slave unit when the YHLS master module suspends communication depends on the Reset/Hold setting for the slave unit.
Response Time This chapter describes the response time of a remote I/O system. Sequence CPU processing time Remote scan time SequenceCPU YHLS master Slave unit module module Input data Internal Read Commu- Input instruction area nication devices Internal Output Commu- Write Output devices...
Page 26
Calculation example: Suppose that 16 slave units are connected to a port for communication at 6 Mbps. Slave unit last address = 16 Tbps 1/transmission speed = 1/6 Mbps = 0.167 x 10 Thus, RST = 354 x 16 x 0.167 x 10 = 944 x 10 (seconds) Slave unit withdrawal or automatic slave unit participation does not affect the remote scan time.
Response Time The response time of a remote I/O system is the sum of the CPU scan time, remote scan time and slave unit internal processing time. Response time for output from CPU module to slave unit The output response time is the maximum time delay before an output of a slave unit turns on after the corresponding internal device of the sequence CPU module turns on.
Page 28
Calculation example Let us calculate the output response time from the CPU module to slave units under the following conditions: Number of slave units Output processing time of slave unit 1 ms max. Sequence CPU scan time 1 ms Master module transmission speed and mode 12 Mbps, full-duplex Slave Slave...
Communication Preparation Flow The following flowchart shows how to prepare for communications. Start Install the YHLS master module See Section 2.3, on the base module. "Attaching/Detaching the Module." Connect slave units to the YHLS See Section 2.2, master module. "External Connection." See Section 7.3, Set up the transmission speed.
List of I/O Relays The YHLS master module has 32 input and 32 output relays for interfacing with the sequence CPU module. Each of the input relays can be set to raise an interrupt. Output Relays Table 6.1 Output Relays Output Relay Description Output Relay Name...
Input Relays Table 6.2 Input Relays Input Relay Number Input Relay Name Description Turns on when communication is started by Communicating 33. Turns off when Y 33 is turned off. Turns on when communication is started if one or Link more slave units are available for communication.
List of Registers The YHLS master module has registers for interfacing with the sequence CPU module. They are grouped into the following four areas: Input data area : For storing data read from slave units Output data area : For storing data to be written to slave units Parameter setup area : For YHLS parameter setup Parameter monitoring area...

7.3.1 Last Address The Last Address parameter specifies the maximum slave unit address value that can be specified for communication. It must be between 1 and 63. If the specified last address is beyond this range, it is assumed to be 63. CAUTION - A slave unit whose address is larger than the specified last address cannot be specified for communication with the master module and, therefore, its input/output...
7.3.4 Monitored Slave List You can specify which slave units are to be monitored for communication error. To monitor error for a specific slave unit, set its corresponding bit to 1. Bit values for slave units beyond the Last Address setting are ignored. When a communication error with a monitored slave unit is detected, the ALM LED lights up and the ALARM relay turns on.
Parameter Monitoring Area Data position No. For port 1 For port 2 Last address Last address Transmission Transmission Parameter Input data area speed speed monitoring area Communications Communications for port 1 mode mode Reserved Reserved Parameter monitoring area Output data area for port 2 Alive slave list Alive slave list...
7.4.1 Last Address This parameter monitors the last address setting for the current communication cycle. 7.4.2 Transmission Speed This parameter monitors the transmission speed setting for the current communication cycle. 7.4.3 Communications mode This parameter monitors the communications mode setting for the current communication cycle.
7.4.6 Failed Slave List (latched) If an error is detected during communication with a slave unit specified for error monitoring, its corresponding bit in the Failed Slave List (latched) is set to 1. Once turned on, a bit is not reset to 0 even when the error condition is removed. To reset a bit, you must overwrite the bit with 0 using a program.
Troubleshooting This chapter describes how to troubleshoot communication failure and other problems. Hardware or Setup Error? Check for the following setup errors before proceeding with troubleshooting: - Are the modules installed correctly? - Are the conditions set correctly? - Is the communication cable correct? - Is the YHLS master module configured correctly? - Are the settings on slave units correct? - Are the power supplies of slave units correct?
