The following conventions are used to indicate and classify precautions in this manual. Failure to heed precautions can result in injury to people or damage to property. ! DANGER Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. ! [. . . ] Pin 1 0 1 2 3 4 5 6 7 OFF ON OFF ON OFF ON OFF ON Pin settings Pin 2 OFF OFF ON ON OFF OFF ON ON Section 4-1 Pin 3 OFF OFF OFF OFF ON ON ON ON Note Unit numbers 0 through 7 are used in C1000H and C2000H Systems. Use numbers 0 and 2 or numbers 1 and 3 for C500 Slaves attached to a C200H Master (to prevent overlapping word assignments). All other PC Systems use only unit numbers 0 and 1. Pin 4: Output HOLD/STOP Mode OFF: STOP mode ON: HOLD mode All output words set to OFF for transmission errors. All output words retain status transmission errors. Transmission errors for Slaves include errors in data from the Master and no-data errors. Note that HOLD mode is not effective for all errors detected by the CPU Unit. 4-1-3 C200H Master Indicators Unit number switch Transmission line terminals 50 Masters and Slaves Indicators LINE ERROR XMT/RCT Section 4-1 Lights for transmission line errors. Setting of 0 or 1 on unit number switch Flashes when any of the Slaves or Remote Terminals in the Master Subsystem are transmitting normally. Goes out if all Slaves and Remote Terminals are abnormal or for errors occurring in the CPU Unit refresh cycle. Goes out if an error occurs in any Slave or Remote Terminal transmitting data or for errors occurring in the CPU Unit refresh cycle. All transmissions will be stopped when this indicator goes out. Setting of 2 or 3 on unit number switch ERROR END RS Lights if an error occurs in any Slave or Remote Terminal transmitting data or for errors occurring in the refresh cycle. Remains unlit as long as all Slaves and Remote Terminals transmitting data are normal. Refer to 7-7 Slave Unit Numbers with Multiple Terminator. Switches and Selectors Unit Number ("Machine No. ") Set to 0 or 2 to set Unit #0; 1 or 3 to set Unit #1. If 0 or 1 is used, transmission will continue even if a transmission error occurs. If 2 or 3 is used, transmission to all Slaves will be interrupted if a transmission error occurs. The only setting necessary for C200H Masters is the unit number. The unit number determines AR area Error flags and Restart bits (see 7-2 Error Codes and Monitoring). 4-1-4 C200H Slaves Two models of C200H Slave are available: C200H-RT201 and C200H-RT202. The C200H-RT201 is switchable between 100/110 VAC and 200/220 VAC; the C200H-RT202 uses 24 VDC. The RT201 is shown below.

Normal transmission Transmission error I/O bus error I/O verification error I/O setting error Normal transmissions are occurring between Slave and Master. An I/O Unit designation on the Slave Rack is wrong. Expansion I/O Rack miss- An Expansion I/O Rack connected to the ing. Slave Rack with I/O Connecting Cable cannot be confirmed by the PC. C200H Slave Switches The DIP switch and terminator selectors are accessed by removing the switch cover on the front of the Slave. Always be sure that the PC and Slave power are turned off before setting the switches.

Pin 6: Pin 6 should always be set to OFF. 4-2 Remote Terminal The procedure for setting the switches in the Remote Interface is exactly the same as in the Remote Terminals. [. . . ] A Rack containing a Remote I/O Slave Unit and controlled through a Remote I/O Master Unit. Slave Racks are generally located away from the CPU Rack. programming device Rack relay-based control Remote I/O Master Unit Remote I/O Slave Unit Remote I/O Subsystem Remote I/O System Remote I/O Unit Remote Terminal series Slave Slave Rack 114 Glossary slot Special I/O Unit A position on a Rack (Backplane) to which a Unit can be mounted. Special I/O Units include Position Control Units, High-Speed Counter Units, Analog I/O Units, etc. In OMRON PC terminology, the word Unit is capitalized to indicate any product sold for a PC System.
