User manual OMRON WIRED REMOTE I-O SYSTEM MANUAL

[. . . ] W120-E1-08 SYSMAC C-series Rack PCs Wired Remote I/O Wired Remote I/O System Manual Revised April 2003 iv Notice: OMRON products are manufactured for use according to proper procedures by a qualified operator and only for the purposes described in this manual. The following conventions are used to indicate and classify precautions in this manual. Always heed the information provided with them. Failure to heed precautions can result in injury to people or damage to property. [. . . ] Use a regular screwdriver to open the cover if necessary. Always be sure that the PC and Slave power are turned off before setting the switches.

STOP mode, i. e. , all output words set to OFF for transmission errors. 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. Only a Remote Interface is shown below. Transmission line terminals + ­ I/O Block connector Indicators Switch cover DIN Rail hook RUN output ­ ON while PC is in RUN or MONITOR mode and no transmission error exists; otherwise, OFF Indicators POWER TR/ERROR Lit when power is supplied and Remote Terminal is operational. Not lit for power irregularities. Lights when on standby or for transmission errors. Goes out for CPU Unit errors (via watchdog timer monitoring). 53 Remote Terminal Switches Section 4-2 Remove the switch cover to access the DIP switch and terminator switch. The switch cover is in a slightly different position on G72C Remote Terminals. + ­ Pins 1 to 6 ON (right): OFF (left): Terminator All others Pins 1 to 5: Word Setting Word numbers are computed as binary numbers with pins 1 through 5 representing the one's place though the 16's place. For example, turning on all five pins would set word 31, i. e. , 20 + 21 + 22 + 23 + 24 = 1 + 2 + 4 + 8 + 16 = 31. Pin 5 must be set OFF for all Remote Terminals, in C120 Systems, i. e. , the highest word that can be set is 15. The word actually allocated to a Remote Terminal depends on the PC that controls it and is computed as shown in the following table. PC C120 and C500 C1000H and C2000H C200H Allocated word Same as switch setting 32 x word multiplier of Master + switch setting Switch setting + 200 Pin 6: Output HOLD/STOP Mode OFF: STOP mode ON: HOLD mode All output words set to OFF for transmission errors. All output words retain status for transmission errors. Transmission errors for Remote Terminals are the same as those for Slaves. 54 SECTION 5 System Installation This section explains how to install Wired I/O Systems and includes information on dimensions, differences between some of the Units, and wiring. 5-1 5-2 5-3 5-4 5-5 Dimensions . 5-1-4 G72C Remote Terminals (Unit: mm) . . 56 56 58 59 59 60 60 61 62 64 55 Dimensions Section 5-1 5-1 5-1-1 Dimensions Masters and Slaves C500 Master (Unit: mm) 34. 5 117 110 93 250 C500 Slave (Unit: mm) 100 34. 5 93 250 56 Dimensions C200H Master (Unit: mm) Section 5-1 35 117 100. 5 130 Rack C200H Slave (Unit: mm) Rack 130 138 112 117 C200H Racks C200H Racks provide either 3, 5, 8, or 10 slots and are used to mount the C200H PC (CPU Racks), Slaves and other Units (Slave Racks), or other Units without a Slave (Expansion I/O Racks). The appearance and parts of the Rack are shown below. Rack and Slave model numbers are as follows: C200H Slaves 100 to 120/200 to 240 VAC (switchable) 24 VDC Racks 3 slots 5 slots 8 slots 10 slots C200H-RT201 C200H-RT202 C200H-BC031-V2 C200H-BC051-V2 C200H-BC081-V2 C200H-BC101-V2 57 Dimensions C200H Rack (Unit: mm) Section 5-1 Dimensions for mounting holes in the following diagram have 0. 2 mm tolerances.

M4 self-rising terminals screws are used for the terminal block. When wiring to the terminal block, use crimp terminals for M4 screws. Do not connect stranded wires directly to the terminal block. Tighten the screws on the terminal block to a torque of 1. 2 N S m. 5-2 Differentiating Units Nameplate, LED, and relay case colors are used to differentiate between Input and Output Blocks and between AC and DC Input Blocks as shown in the following table. --Input Blocks Output Block (DC) (AC) (DC) Nameplate Red Red Yellow LEDs Green Red Green Relay Case Green Red Clear I/O Block nameplates are color matched with PC I/O Units. LED positions and relay orientation also differ between Input and Output Blocks and can be used to differentiate between them. Relays are also positioned to assist in following signal flow. 60 I/O Block Connections Section 5-3 5-3 I/O Block Connections Relay hooks Input Block Remote Interface connector I/O slim relays Nameplate (red) Power terminal 0 C0 1 C1 2 C2 3 C3 4 C4 5 C5 6 C6 7 C7 8 C8 9 10 11 12 13 14 15 LEDs (green for DC Terminals, red for AC Terminals) C9 C10 C11 C12 C13 C14 C15 DIN Rail hooks Unused terminal Input terminals Internal Connections G7TC-ID16 (for DC input) +­ 9 19 10 20 Input relays G7T-1122S 1 2 3 4 5 6 7 8 11 12 13 14 15 16 17 18 C0 0 C1 1 C2 2 C3 3 C4 4 C5 5 C6 6 C7 7 C8 8 C9 9 C1010 C11 11 C1212 C1313 C1414 C1515 G7TC-IA16 (for AC input) +­ 9 19 10 20 Input relays G7T-1122S 1 2 3 4 5 6 7 8 11 12 13 14 15 16 17 18 C0 0 C1 1 C2 2 C3 3 C4 4 C5 5 C6 6 C7 7 C8 8 C9 9 C1010 C11 11 C1212 C1313 C1414 C1515 61 Mounting and Wiring Precautions Output Block Section 5-4 LEDs (green) Remote Terminal connector I/O slim relays Nameplate (yellow) Power terminals 0 C0 1 C1 2 C2 3 C3 4 C4 5 C5 6 C6 7 C7 8 C8 9 10 11 12 13 14 15 C9 C10 C11 C12 C13 C14 C15 Unused terminal DIN Rail hooks Output terminals Relay hooks Internal Connections G7TC-OC16 9 19 10 20 +­ Output relays G7T-112S 1 2 3 4 5 6 7 8 11 12 13 14 15 16 17 18 C0 0 C1 1 C2 2 C3 3 C4 4 C5 5 C6 6 C7 7 C8 8 C9 9 C1010 C11 11 C1212 C1313 C1414 C1515 5-4 Mounting and Wiring Precautions Remote Interface and I/O Blocks are generally mounted to DIN Rail using two End Plates (model number PFP-M). Four short bars are provided for common points. Output capacity limits the number of common point to four.
