This manual describes the means and Units necessary to construct a Wired Remote I/O System con- sisting of at least one Remote I/O Master Unit and one or more Remote I/O Slave Units or Remote Terminals. (The term “Wired” refers to the links used to create the Remote I/O System, e.g., that be- tween a Remote I/O Master Unit and a Remote I/O Slave Unit.) Remote I/O Systems reduce wiring... - Page 9 This section provides general precautions for using the Wired Remote I/O System and related devices. The information contained in this section is important for the safe and reliable application of the Wired Remote I/O System. You must read this section and understand the information contained before attempting to set up or operate the Wired Remote I/O System.

Safety Precautions WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing so may result in electric shock. WARNING Do not touch any of the terminals or terminal blocks while the power is being supplied. -
Page 11: Operating Environment Precautions
The PC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system. - Page 12 Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may break the cables. Do not place objects on top of the cables or other wiring lines. Doing so may break the cables.

You must therefore confirm that the overall machine or equipment complies with EC Directives. 4. Remote I/O products that comply with EC Directives have configurations with less than 30 m of I/O wiring, and less than 10 m of power supply wiring. -

Section 1-1 Remote I/O Systems A Remote I/O System directly involves only one PC and the program in it and through it a large number of I/O points can be controlled a greater distance from the PC. This is achieved by mounting a Remote I/O Master Unit to the CPU Rack to control I/O points located possibly many kilometers away. - Page 17 Section 1-2 Wired Remote I/O Systems A Master is mounted to the CPU Rack or an Expansion I/O Rack; a Slave is mounted to a Backplane to form what is called a Slave Rack. To a Slave Rack is mounted the same other Units as those mounted to the CPU or Ex- pansion I/O Rack, with only a few exceptions (e.g., Link Units other than...

Page 19: Section 2 System Design
Although there are many possible Remote I/O Systems that can be built out of Masters, Slaves and Remote Terminals, each System is limited by the capacity of the PC and the nature of the other Units in the System. Section 2-1 describes System configurations based on the C500-RM201 Master and C500-RT201 Slave (i.e., for C120, C500, C1000H, and... -
Page 20: Basic System
All Units can be combined in any fashion and connected in any order as long as they are in series and the Master is on one end of the line. I/O Blocks are mounted to Remote Interfaces. - Page 21 G7TC-OC16 24 VDC G71-OD16 24 VDC Maximum Number of The number of Units in any one System is limited by the capacity of the PC. Connectable Remote I/O Detailed limitations are provided in the following table. These totals include Units all Optical and Wired Master Subsystems controlled by the PC.
- Page 22 C500 C120 *The total number of I/O points in a C1000H System can be up to 2,048, as long the number of I/O points on the CPU Rack and Expansion I/O Racks connected to the CPU Rack (i.e., not I/O points on Slave Racks) is limited to 1,024.
-
Page 23: C120 Systems
In C120 Systems, up to four Masters can be connected to the same PC, and up to two Slaves and 16 Remote Terminals can be connected to any one Master. Note that a Master in a C120 System must be mounted to an I/O slot on a C500 Expansion I/O Rack. -
Page 24: C500 Systems
C500 PCs provide 512 I/O points. This means that the total number of points used in the System must be 512 or less. If, for example, 512 points are con- trolled by one Master connected to a C500 PC, no more Masters or I/O points can be employed for that C500 PC. -
Page 25: C1000H And C2000H Systems
When a Remote I/O System is included, C1000H and C2000H PCs provide 2,048 I/O points. This means that the total number of points used in the Sys- tem must be 2,048 or less. If, for example, 2,048 points are controlled by four Masters on C1000H and C2000H PCs, no more Masters or I/O points can be employed on the PCs. -

Wired Remote I/O Units. The entire Master Subsystem, from Master to termi- nator, must still be connected in series. Up to 8 Link Adapters (4 pairs) can be used for each Master. To take full ad- vantage of an optical link, shorten wire links as much as possible, even to the point of placing the Link Adapter on the same control panels as the Remote I/O Units. -

Note that if there was no Master on this Rack and the Optical I/O Units and Slave Rack were connected through the I/O Link Unit, they would become the last Units in the Optical Remote I/O Subsystem controlled by the CPU Unit at the upper left, and be controlled by it. - Page 31 Expansion I/O Racks, both connected to a CPU Rack and to Slave Racks. Although normally not shown in system diagrams for Link Sys- tems, Expansion I/O Racks can be used to increase the number of I/O Units mountable at any one location.

Page 36: Unit Numbers And I/O Word Allocation
Word allocations on Racks in Remote I/O Systems follow basically the same pattern as the PC to which the Master is mounted, i.e., by the mounting order of and by the number of words required for each Unit mounted for C120, C500, C1000H, and C2000H Systems and by fixed slot words in C200H Sys- tems. -

I/O bus are acknowledged. All following operation is based on this initial check. Therefore, if a Unit is not attached properly or if the power to a Unit is not on when this check is performed, that Unit will be ignored dur- ing actual operation. - Page 38 For example, suppose word 28 is set on a Remote Terminal and word multi- plier 2 is assigned to the Master of that Remote Terminal. The I/O word allo- cated to the Remote Terminal, viewed from the PC, is computed as follows:...

Before setting word multipliers, set the mode selector to PROGRAM. Word multipliers must be assigned only to the Masters to which Remote Terminals are connected.

Slave Rack. I/O slots on the Rack would be, from left to right, 50, 51, 52 ... 58, and 59. Slot words do not change even if an I/O Unit is not mounted in every slot. Slot words not used on shorter Racks can be use as work words. - Page 46 This example System shows word allocations for two C200H Masters, one on and Slaves the CPU Rack and one on an Expansion I/O Rack, and four of the maximum possible five C200H Slaves. (The unallocated I/O words may be used as work words.)

Page 51: Setting Procedure
After the terminator check indicator(s) on the Master(s) goes out, enter the I/O table (see note 3) through the Programming Console and then verify the I/O table. If a terminator is not found, CPU WAIT’G will be dis- played on the Programming Console. Once the I/O table has been en- tered, it is not necessary to reenter it each time power is turned on, un- less there is a change in it. -
Page 52: Delayed Activation Of Slaves
Delayed Activation of Slaves The following examples illustrate program sections that can be inserted to start System operation when power to a Slave is turned on after its Master has been turned on. Note, however, that the normal procedure, i.e., turning on all Slaves before their Masters, must be followed when creating the I/O table. -

Page 116: C When Using Cs1-Series Pcs
CIO 3000 to CIO 3049 are allocated to C200H Remote I/O Slave Units based on their unit number settings (0 to 4) in 10-word blocks. From each 10-word block, 16 bits are allocated to each slot (even if the slot is not used) of the Slave Rack starting from the left (the slot farthest from the Slave Unit). - Page 117 Hardware Setup 1, 2, 3... 1. Mount a Remote I/O Master Unit to a CS1 CPU Rack, a C200H I/O Expan- sion Rack, or a CS1 Expansion Rack (not a SYSMAC BUS Remote I/O Slave Rack). Up to two Masters can be mounted for a basic system. (There are no restrictions on the mounting position.)

With most PCs, the CPU Rack is the only Rack that provides linkable slots. data area An area in the PC’s memory that is designed to hold a specific type of data, e.g., the LR area is designed for to hold common data in a PC Link System. distributed control A automation concept in which control of each portion of an automated sys- tem is located near the devices actually being control, i.e., control is decen-...
