The JW-32CUM1 is a control module for the JW30H programmable controller. It has a built in
communication function. Its control section is completely compatible with all JW30H series modules
(equivalent to JW-32CUH1). It occupies two slots (the same as the JW-32CUH1) on a basic rack panel.
Just install it on the proprietary JW-34KBM basic rack panel and the compactly designed JW-32CUM1 will
provide you with communication. By installing a JW-32CUM1, the system does not need a network
module, which saves space and cuts cost.
[1] DeviceNet master function (full time use is possible)
The JW-32CUM1 can connect to slave stations that conform to DeviceNet specifications (common
throughout North America). This is a useful function for common use in facilities both inside and outside
Japan.
- The JW-32CUM1 employs a multi-drop system that can connect between nodes using a single
proprietary cable, significantly reducing electrical wiring labor and material costs. The system also can
contain branches by using a T-branch tap.
- The communication time can be reduced by dividing a system into groups.
- The scan list editing function affords easy I/O allocation of slave stations, so there is no need for a
configurator to make programs.
[2] Select any one of four communication functions with switches
Communication with SHARP programmable controllers is possible by using a twisted-pair cable. Select
any one of four master station functions: Remote I/O, data link DL1/DL9, and M-net.
(1) Remote I/O master station function
Using the JW-32CUM1 as master station, you can configure a remote I/O system as slave station
using I/O modules (such as the slave module JW-21RS) for the JW20H/30H.
(2) Data link DL1 master station function (N: M method)
Making effective use of memory, the JW-32CUM1 provides interlocks between each process step and
a distributed control operation.
(3) Data link DL9 master station function (1: N method)
This function does not support communication between slave stations. Each slave station must
communicate with a master station. Use this function to construct a system with lots of link points and
hierarchic control.
(4) M-net (master station) function
Construct a network with link modules mounted SHARP programmable controllers, other
manufacturers' programmable controllers, measuring instruments, and industrial robots that are M-
net compatible.
[3] Computer link (equipped with 2 ports)
The JW-32CUM1 is equipped with two communication ports for RS-232C and RS-422A communications
(the COMM2 port is for RS-232C use only). Using these ports, the JW-32CUM1 can communicate with a
personal computer or a programmer, etc.
