Selection of Controller or Control board

Select a S-LINK V controller or a S-LINK V control board optimum for the upper machines (PLC, PC, PCI bus computer, VME bus computer, open network).

I/O Control Points

The system needs the following I/O control points. Design the system considering these points.

●●Each controller or control board can control up to 256 nodes (number of I/O units connected to the system) and 512 points (512 points × 2 for the SL-VVMES2). To control more than 512 points (512 points × 2 for the SL-VVMES2) of I/O device, connect two or more controllers as the other systems.

●●To cope with various PLC connection types of various manufacturers, we can provide 8 types of PLC input connectors and 7 types of PLC output connectors. For a detailed description, refer to pages 159 and 160. Each PLC I/O connector has 32 points for any model.

Each system needs one controller or one control board.

NOTE Two or more controllers or control boards cannot be connected to one system.

The above described number of I/O control points (512 points or 512 points × 2 for the SL-VVMES2) and the number of nodes (256 nodes) are the maximum values.

This means that these values depend on the total cable length and the conditions of the connected machine (total current consumption, voltage drop, etc.).

For a detailed description, refer to pages 16 to 25.

Transmission Distance

The following two types of cables can be used for the S-LINK V system.

●●Exclusive 4-core flat cable (recommended cable)

●●4-core VCTF cable (0.3 to 2.0mm2, non-shielded) commercially available

Note: The VCTF cable is the vinyl cabtyre cable that conforms to the requirements of JIS C 3306 ‘Polyvinyl chloride insulated flexible cords.’

To wire the S-LINK V system, use 4-core cables so that the wire system can consist of 2 power supply lines (+24V, 0V) and 2 signal transmission lines (D, G).

The cable length depends on the total cable length and the transmission distance.

Outline of Design

			●●The main line is the longest route distributed from the controller or control board.
		NOTE
			●●The branch lines are the routes branched from the main line.

The total cable length should satisfy the conditions shown in the following table:

Transmission mode	Total cable length (m)
A	100
B	400
C	1,600

The maximum transmission distance (between D and G) is as follows:

●●Mode A: 50m

●●Voltage drop between +24V and 0V is not considered. For this reason, calculate this volt- NOTE age drop value, and use a local power supply unit, etc. to prevent voltage drop.

For a detailed description, refer to page 23.

●●The conductor cross section of the exclusive 4-core flat cable SL-RCM□ is 0.5mm2.

●●Wire the S-LINK V system while observing the communication distance specifications described above. In addition, use the cables that satisfy the specifications described above.

●●To select applicable cables, refer to the section describing cables. For a detailed description, refer to page 157.

●●The picking switch SL-VPK0□ cannot be used in mode A (transmission mode).

Outputting Error Signals

If the controller is equipped with the error signal output function, the controller can output an error signal after detection of an error.

To output an error signal, the S-LINK V system will be turned on properly. If an error occurs, the NPN output transistor will be turned off.

For each type of error, you can select whether the error signal should be output. For the Troubleshooting, refer to page 165.

For the error, refer to page 166.

Connection of End Unit

CAUTION

Each system needs at least 1 SL-VEU end unit. If the SL-VEU unit is not connected, the system may not operate properly.

If the cable lengths are the same, connect the end unit to the line having fewer nodes (units).

Be sure to connect 1 SL-VEU end unit to the end of the main line.

If the branch line length exceeds 80% of the maximum transmission distance, connect 1 SL-VEU unit to the end of the branch line, too.

Up to 2 SL-VEU end units can be connected for 1 system.

<If the branch line length is equal to the main line length>

Same length (Note 1)

Maximum transmission distance

Connect the end unit to the main line and branch line, respectively.

80% of the main line length or more

Notes: 1) The maximum transmission distance depends on the cable conductor cross section and the number of nodes. For the maximum transmission distance, refer to page 17.

2)Even if the cable lengths are the same, if both the main and branch line lengths exceed 80% of the maximum transmission distance, connect two SL-VEU end units.

Selection of Control Cable and Connector Link Cable

Control cable selection method: (For use of SL-VCU1 only)

Check the distance from the SL-VCU1 to the PLC I/O connector, and then select the applicable control cable: SL-VC1000 (1m long) or SL-VC2000 (2m long).

One control cable is needed for every 8 PLC I/O connectors.

Connector link cable selection method: (For use of SL-VCU1 only)

The PLC I/O connector installation direction (vertical) and layout depend on the PLC manufacturers.

Check the connection distance of the PLC I/O connector, and then select the applicable connector link cable: SL-VF70 (70mm), SL-VF150 (150mm), or SL-VF250 (250mm).

For a detailed description, refer to page 176.

Power Supply Capacity of System

Calculation of Voltage Drop Value

The transmission cables of the S-LINK V system may cause voltage drop due to the conductor resistance of the cables themselves. For this reason, calculate the voltage drop value between +24V and 0V, and supply the rated voltage to all the S-LINK V I/O units. However, it is not necessary to consider the voltage drop between the D and G, and that of the control cables and connector link cables.

CAUTION

Use of a longer cable will cause more voltage drop. If the voltage drops below the rated voltage, the I/O units will not work. In this case, use the local power supply unit.

Elongation of the transmission distance will cause more voltage drop at the line end (between +24V and 0V).

Voltage drop (V) = Cable length (m) × 2 × conductor resistance (Ω/m) × current (A)

Relation between the ambient temperature and allowable passing current when exclusive S-LINK V cable SL-RCM100□ / RCM200 or SL-CBM100 / CBM200 (conductor cross section = 0.5mm2 for each cable) is used.

Rated voltage (V)

CAUTION

The rated voltage depends on the unit. Check the rated voltage, and then select the right power supply unit and cables.

Supply the rated voltage to each unit.

●●Since the rated voltage to be supplied to the controller is +24V (-5%), the voltage supplied to the controller should not be dropped below the following value:

24 - (24 × 0.05) = 22.8V

●●Since the rated voltage to be supplied to the I/O units and end unit is +24V (-10%), the voltage supplied to these units should not be dropped below the following value:

24 - (24 × 0.1) = 21.6V

23

Power Supply Capacity of System

<![if ! IE]>

<![endif]>Chapter 1

Necessity of Local Power Supply Unit

The 24V DC power supply unit that drives the system uses either the centralized power supply method (use of only one power supply unit) or the decentralized power supply method (use of additional local power supply unit) to supply power to each unit.

At first, calculate the total current consumption value (sum total of current consumption values of all units ‘+’ sum total of load current values of I/O devices).

After that, from the obtained calculation result, cable length, and conductor resistance, calculate the voltage drop value, and determine the voltage to be supplied to each unit.

If the voltage supplied to each unit is above the rated voltage (22.8V or more for the controller, 21.6V or more for the I/O unit), you can design the system using the centralized power supply method.

If the voltage supplied to a unit is out of the rated voltage range, connect a local power supply unit, and use the local power supply method.

Designing of system using local power supply method

CAUTION

To use a local power supply unit, turn on the local power supply unit first, and then turn on the main power supply unit, or turn on these power supply units at the same time.

If the main power supply unit is turned on first, the system may not operate properly.

In the following cases, connect a local power supply unit:

●●The communication distance is too long, and voltage drop is too large.

For this reason, it is not possible to supply the rated voltage to the I/O units. ●●A 2-core cable is used for connection of the I/O unit (for the D-G line only).

●●The main power supply unit and the local power supply unit should be the small capacity type. ●●An I/O device that generates a large noise should be used.

Notes: 1) The conductor resistance values shown in the above table are reference values.

To determine the conductor resistance values for the actual cables, contact the cable manufacturer.

2) The conductor cross section of the exclusive 4-core flat cable should be 0.5mm2.

VA (residual voltage in ON mode) of GX-12MU = 3V or less

Specified operation voltage range of GX-12MU = 12 to 24V DC +10– 5 % = 10.2 to 26.4V DC Minimum load current of GX-12MU = 3mA
