Point2. User-friendliness

Removable terminals for easy set up (except for 10-point type)

Replacement of the MICRO-EH can be accomplished in a fraction of the time.

Easy installation by snapping on a DIN rail or screwing onto a panel

Terminal protective covers are hinged and can stay open for easy wiring. Terminal layout indication on the front panel can be read even when the protective covers are open.

Removable terminals

Point3. Compatibility with H/EH series PLC

Same programming software for utilization of valuable existing user programs -LADDER EDITOR for Windows®

[Pro-H (IEC61131-3) is also available.]

LADDER EDITOR

Windows is a registered trademark of Microsoft Corp. in the U.S. and other countries.

Point4. Conformity to global standards

CE, UL, cUL, and C-Tick approvals

CE, UL, cUL, and C-Tick approvals

Point5. Network compatibility

RS-232C port as standard (Port 1)

Communication speed can be selected from 4800, 9600, 19200, and 38400 bps. *1
Modem control function is incorporated. (except for 10-point type)

*1. Standard procedure (transmission control procedure 1) and simplified procedure (transmission control procedure 2)

  • By connecting the port 1 with a peripheral unit, the created programs can be transferred, the programs stored in the CPU can be read/verified, and CPU operating status can be monitored. In addition, a monitoring system that connects the display device, etc. can be configured.

RS-232C port as standard (Port 1)

  RS-422 RS-485
Transmission control procedure 1 1:1 Possible Possible Possible Possible
1:n
Transmission control procedure 2 1:1 Possible Possible Impossible Impossible
1:n

RS-422/485 port as standard for 23-/28-point type (port 2)

Either RS-422 or RS-485 can be selected by the connection wiring.

  • 1:n station communication by HI-PROTOCOL is possible via the port 2 *2 . By creating and including a control procedure based on HI-PROTOCOL on the personal computer that will become the host, it is then possible to control 32 units from one host.

*2. When performing 1:n station communication using port 2, the transmission control procedure that can be used is restricted by the interface. Since transmission and reception are started up at the same time in transmission control procedure 2, it is not possible to perform communication with an RS-485 interface. The table shown right reflects the correspondence between transmission control procedure and interface.

Point6. Environmental friendlines

Laser marking system is employed for the MICRO-EH series to eliminate sticker type nameplates.
ABS material is used for outer case of the MICRO-EH for easy recycling.
Battery-less operation with flash memory helps reduce waste.
