Chapter 1 Outline

Using network module JW-20CM, you can construct a communications system (satellite net) which can easily send and receive an ON/OFF signal (machine information) and numerical data (production data) between PCs and a host computer using equipment control. Using remote I/O slave module JW-20RS, you can construct a remote I/O system as master station for PC that installed JW-20CM. PCs which can use JW-20CM and JW-20RS are W70H/100H, JW50/70/100, and JW50H/70H/100H.

① Data link/computer link function

This function enables to send and receive ON/OFF signals and numeric data between modules on a network (satellite net) which is connected PCs and personal computers having network module ZW-20CM/JW-20CM/JW-22CM, network module ZW-98CM/ZW-20AX, and satellite net board Z335J.

② Remote I/O function

If remote I/O slave module ZW-20RS/JW-20RS are mounted on I/O modules located separately, one PC having a network module JW-20CM can control these slave modules. (Connectable maximum 63 modules of slave stations.)

· In the remote I/O function, the remote I/O can choose either of synchronous or asynchronous for sending and receiving data with slave stations.

Synchronous type: Slave station scans input/output operation one time for each operation of

the PC.

Asynchronous type: When PC's operation time is longer than data transfer required time of the

remote I/O, the slave station scans input/output operation one time for each operation of the PC. When PC's operation time is shorter than the data transfer required time of the remote I/O, the slave station operate input and output one time for several operation of the PC.

③ Remote programming/remote monitor function

By constructing a satellite system using the JW-20CM, you can program and monitor other station’s PC’s (master station’s PC in case that remote I/O function) on the satellite system using a support tool.

· These remote programming and remote monitor functions are also available beyond one hierarchical layer difference (satellite net ←→ satellite net, satellite net ←→ SUMINET-3200).

Chapter 2 Safety Precautions

2-1 Installation

● Do not install or store the JW-20CM in the following conditions.

• Direct sunlight

• Ambient temperature exceeding the range of 0 to 55 ˚C (Storage temperature : -20 to 70 ˚C)

• The relative humidity exceeding the range of 35 to 90%.

• Sudden temperature changes which may cause condensation.

• Corrosive or inflammable gas

• Vibration or hard jolts

●Prior to installing or detaching the JW-20CM, make sure to turn OFF the power supply to the PCs.

● All screws must be tightened firmly.

2-2 Wiring

● Make sure to use only the recommended types (see page 6 · 1) for cables, connectors, and crimping

tools.

●When using connectors for branch or joint lines, provide jackets to protect connectors.

(When a connector touches with an external enclosure or the like, a communication error may occur.)

“T” jacket

(insulation cover)

“L” jacket

(insulation cover)

● Do not connect the ground terminal of the power supply module together with other equipment’s

ground lines. Make sure to provide class-3 grounding. When the JW-20CM is used without connecting a class-3 grounding, malfunctions by noise may occur.

● Communication cables should be arranged as far from any high voltage lines and strong power lines

as possible. Do not lay the communication cable parallel or proximate to these lines.

2·1

● Communication cables should be laid from the master station to the slave station one by one.

Multiple wiring from one point or wiring without terminators may cause communication errors.

Joint using a connector

● Arrange total cable length within 1 km.

● Arrange branch cable line from a trunk within 400 mm.

● Prior to any electric welding around the JW-20CM, take out the coaxial cable from the JW-20CM.

While the coaxial cable is connected to the JW-20CM, any electric welding nearby the JW-20CM will cause the welding current to enter the JW-20CM and may damage part of its circuit pattern.

2-3 Treatment

● For ventilation, holes are provided in the cabinet to prevent a temperature rise. Do not block the

ventilation holes. Good ventilation is necessary.

● Never allow a liquid such as water and chemical solution and a metallic object like a copper wire

inside the JW-20CM to avoid a possible hazard. Otherwise, it may be a cause of machine trouble.

● When a trouble or abnormal condition such as overheat, fume, or smoke is met, stop the operation

immediately, and call your dealer or our service department.

2-4 Static electricity

In extremely dry circumstances, the human body may have excessive static current. This excessive static current may damage parts in the JW-20CM’s PC board. Therefore, prior to accessing the JW20CM, touch your hand to a grounded piece of metal to discharge the static current in your body.

2-5 Maintenance

Use a clean, dry cloth when cleaning the JW-20CM. Do not use volatile chemicals such as thinner or alcohol as it may result in deformation and color fading.

ring) back and forth and the cable holder moves back and forth accordingly. Confirm this movement of the stripper first. To hold the stripper, put your forefinger through the hole and move the cam while pushing back and forth with your thumb.

Set the operation range of the cable holder by moving

the slider at the bottom of the body. Move to the left to increase pressure.

Blade cassette

In this example, set the slider to the cam wheel side’s end (right side) to set the pressure to low.

Front

Blade (slashed area)

Cam wheel

Rear

Adjust the cutting depth of the blade by turning the two screws at both ends of the screw holder. Set the blade position to within 1 mm from the cutting surface of the blade cassette prior to adjusting the cutting depth. For the cutting depth adjustment, use the “blade setting gauge” supplied as an accessory and match the blade position with the caved position of the gauge. Then move the cam wheel forward and secure firmly. Turn right lightly both adjustment screws at either end of the screw holder for adjustment. (Be careful not to break the blade setting gauge as it is made of aluminum.)

(Fine adjustment is required to get the optimum cutting depth.)

From the previous page

<Cutting of coating, external conductor,

and insulator>

Put a coaxial cable while remaining approximately 10 mm into the cable stripper and securely tighten the cable with the middle finger, ring finger, and little finger of your left hand in order to hold stable during turning the stripper. Put your right hand forefinger into the cam wheel and execute the procedure in order from step 1 below.

Internal conductor

(annealed copper single wire)

Insulator

(semi-transparent)

While holding the coaxial cable with your left hand, grip the cable stripper so that it keeps a right angle against the coaxial cable, and press out the cable stripper with your left hand’s thumb.

When the adjustment of the blade is not required

Step 1

Press the cam wheel forward 3 times and turn the stripper in the direction of arrow 2 to 3 times.

Step 2

Press the cam wheel forward 1 time and then turn the stripper in the direction of arrow a further 2 to 3 times.

Step 3

Press the cam wheel forward 1 more time and turn the stripper in the direction of the arrow another 2 to 3 times.

<Removal of coating, external conductor,

and insulator>

If the stripper cannot be removed smoothly, adjustment of the blade is not appropriate. In this case slide the cam wheel backward and remove the coaxial cable. Then adjust the blade.

When the cutting depth is too shallow or too deep, and damages the external conductor or the internal conductor, turn the screws on the screw holder and adjust the blade depth a little.

Slightly widen the external conductor of the coaxial cable, which is crimped to a contact on the internal conductor, in order to smoothly enter the shell inside the external conductor. Press in the external conductor end of the coaxial cable to just before the crimping part of the shell and put the sleeve into the crimping section. Then press in the coaxial cable until a “click” sound can be heard. Confirm that the contact end point touches your finger cushion.

Insulation test of shell and contact

Using a tester, check the conductivity between the internal conductor and the external conductor in the connector. When the indication of the tester shows ∞ ohms, the insulation is appropriate.

Conductivity test

After short-circuiting the one end of the connector crimped to the coaxial cable, check that conductivity is attained.

7-1 Cable trunk and branch lines

① On the illustration of the cable wiring below, a bold line means a trunk and the thin lines branched

from the trunk with a “T” shape are called branch lines.

Branch line

400 mm max.

Trunk cable

② The length of branch lines branched from the trunk should be within 400 mm.

400 mm

③ Total cable length should be within 1 km.

7-2 Relaying of trunk cables

① To relay trunk cables, use the straight joint (ME-JJ-01).

ME-JJ-01

② Relaying of trunk cables should be limited to indispensable cases only. Inadvertent relaying of

trunk cables may cause a communication fault such as a weakened signal level due to contact resistance in the junction connector (straight).
