Chapter 2: Precautions for Use
When using the JW-32CUM1 (JW-34KBM), pay attention to the following points (1) to (6) that describe
differences from other control modules for the JW30H series (such as the JW-32CUH1).
(1) Installation
The JW-32CUM1 can be installed on a JW-34KBM basic rack panel. It cannot be installed on other
basic rack panels (such as the JW-34KB).
Other control modules, such as JW-32CUH1, cannot be installed on the JW-34KBM basic rack panel.
(2) Allocation of relay numbers
With a JW30H system that is constructed using the JW-32CUM1 (JW-34KBM), the first rack number
0 address must be ｺ0004 (relay number 00040). Slot numbers for installing I/O, special I/O, I/O link,
and other option modules must start with the number "2."
(3) DeviceNet communications for the JW-32CUM1
- The node address is fixed to "0: Master."
- The data memory area used for the DeviceNet is fixed. (The Module No. switch is fixed to 0.)
(4) General-purpose communications with the JW-32CUM1 (remote I/O, data link DL1/DL9, and
M-net)
- The station number is fixed to "0: Master station."
- The data memory area for general-purpose communications is fixed. (The Module No. switch is fixed
to 0.)
- When using the JW-32CUM1 with remote I/O, a JW-21CM cannot be used as a remote I/O master
station on the same JW-34KBM basic rack panel.
(5) Option modules
Up to four option modules (e.g. the JW-22CM) can be installed on the JW-34KBM (JW-32CUM1). Set
the module No. switch on option modules to some number other than 0.
(The general-purpose communication section of the JW-32CUM1 uses the 0 area.)
(6) I/O link master modules and DeviceNet master modules
- Only one JW-23LMH can be installed on a JW-34KBM (JW-32CUM1). Only operation modes 7 and
8 can be used.
(The DeviceNet section of the JW-32CUM1 uses the areas for operation modes 1 to 6.)
- Up to three JW-20DNs can be installed on the JW-34KBM (JW-32CUM1). Set the module No. switch
to some number other than 0.
(The DeviceNet section of the JW-32CUM1 uses the 0 area.)
The precautions below apply to the JW30H (with a JW-32CUM1) and are the same as for other control
modules (JW-32CUH1 etc.).
(7) Installation
Avoid keeping the JW30H in the following conditions:
- Direct sunlight.
- Relative humidity which exceeds 35 to 90 %. No condensation due to rapid temperature variation.
- Corrosive and flammable gases.
(8) Operation
- Prepare an emergency stop circuit at the external relay circuit, and connect the halt output from the
JW30H. (The halt output is installed in the power supply module.)
- Don't handle switches and connectors excessively by force.
(9) Grounding
Prepare a class-3 grounding of the JW30H separately. Never co-ground with high power equipment
grounding lines.
(10) Installation
- Securely fasten the retaining screws in each module, and confirm again that it is fastened prior to
supply power. Looseness of screws may cause malfunction.
- Firmly connect cable (I/O expansion cable), connecting to the basic/expansion rack panel. Confirm
connectors are fastened prior to supplying power. Looseness may cause malfunction.
- Each module has a ventilation hole to allow for cooling. Do not block the holes.
- Install the JW30H horizontally against a control panel (parallel, wall-mount installation), otherwise
(vertical, wall-mount installation) temperature increase may occur.
(11) Wiring
- Be aware not to cross the connection polarity of 5 VDC on the expansion rack panel. Otherwise,
rack panel and I/O module etc. may be damaged.
- Keep the input/output lines away from high voltage or strong current lines such as power lines.
