9.377 Moxa-ioLogik-1200

This page describes the device driver and the device window for the Moxa ioLogik E12xx data acquisition module family. The device driver monitors and controls the digital inputs/outputs of various ioLogik E12xx modules. Analog or temperature sensor input functions are not covered by this driver, neither are counter/timer timer function of the some modules. The driver can be used together with the following modules:

• E1210 (16 inputs)
• E1212 (8 inputs, 8 outputs)
• E1214 (6 inputs, 6 relay outputs)

The Moxa-ioLogik-1200 device driver is part of the sat-nms framework for M&C of plain digital I/O functions. Monitoring alarm circuits or controlling waveguide switches are indicatives for applications of this framework.

The application configuration normally does not access the Moxa-ioLogik-1200 device driver directly (except to access the temperature readings). There are a couple of application level logical devices (e.g. Input , Output or WG-Switch ) which may use the SatService-IO-FEP device driver as a low level driver to access the physical I/O ports.

Input ports

The variable I00001 refers to the input ports provided by the device. The least significant bit denotes the state of DI0.

The variable reports the physical state if the input. A bit is set to '1' if the input is open or externally driven to high level. The bit reads '0' if the input is connected to GND or externally driven to low level.

Output ports

The variable 'Q00001' reports the actual state of the digital outputs and also sets the output states. The least significant bit in the variable corresponds to output DO0.

Configuration settings

If used with the sat-nms framework for M&C of plain digital I/O functions, the Moxa ioLogik module acts like an unprogrammed PLC device. It is intended, that the device driver processes switch settings and changes of input circuits as fast as possible. The following settings are necessary to achieve this:

• When defining the device in the device setup window , there must not be defined any other devices beside this module for this interface.
• The Moxa ioLogik modules are controlled through Modbus/TCP. The device's IP address must be set as an interface name like with serial devices controlled through a network terminal adapter: "aaa.bbb.ccc.ddd:502" where 502 is the standard Modbus/TCP port number.
• The IDLE time for the interface must be set to 200 msecs for a fast response of the driver.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- Shows / commands I/O port states.
• --- The faults page.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the device.
