MMTCP8AI

MMTCP8AI - ANALOG INPUTS

The Analog Input modules are supplied as either a current input module (MMTCP8AI/I) or a voltage input module (MMTCP8AI/V). The inputs are isolated from the logic and share a common negative terminal.

The standard setting for the MM8AI/I module is 0 - 20mA input current which represents an output value of 0 - 4095 (12 bits) in the corresponding Modbus register. 4 mA would give a reading of 819 ± 1LSB.

The same applies to the MM8AI/V module. An input voltage of 0 - 10Volts represents an output of 0 - 4095 and 2 volts would give a reading of 819 ± 1LSB. An input range of 0(1) to 5Vdc is available by removing the jumper link located on the analogue board inside the enclosure.

Each MMTCP8AI Module has a unique Ethernet IP address which must be programmed into the PC or PLC. The IP address in the MMTCP8AI Module is configured via the Web Server. Any standard Web browser such as Internet Explorer can be used to access the web pages were configuration is carried out. The converters are factory programmed with a default IP address of 169.254.111.111. This address must be changed before the converter is added to an existing network.

CONFIGURATION

The Web page address "169.254.111.111/ip.htm" is entered into the address line of the browser window to access the configuration page. This page allows you to change the IP address of the MOD-MUX TCP Module and to enter a Module Description Name and Input Names for identification/maintenance purposes.

IP Address: The new IP address can be entered into the web page as shown above. After this has been done, you must click the Submit button to send the values to the MOD-MUX TCP Module. The screen will now be updated and if successful will continue to display the new IP address. The new IP address will only be effective after the MOD-MUX TCP Module power has been switched off and on again. This feature allows you to check that the correct IP address has been entered before being activated. If the IP address has been entered incorrectly and the power has not been switched off, it is possible to re-enter the correct IP address. If the power has been switched off and back on again, the MOD-MUX TCP Module will not communicate until you enter the new IP address into the address line of the browser window.

	Module Name: This field allows you to enter a module description name into the MOD-MUX TCP Module. This is an identifier for diagnostic/maintenance purposes and is chosen to best describe the MOD-MUX TCP Module in the system by name or number.
	Input Names: These fields allow you to enter an input description name into the MOD-MUX TCP Module. This is an identifier for diagnostic/maintenance purposes and is chosen to best describe the particular input by name or number.

VIEWING WEB PAGES

To view the default Web page in the MOD-MUX TCP Module, start the Web browser and type "169.254.111.111" into the address line of the browser window. The main page will now be displayed in the browser window.

	Input Number: This refers to the actual input number on the terminals of the module.
	Input Name: This is the name that was entered in the configuration page to best describe the inputs.
	Input Value: This is the current value of the inputs. To get an updated reading it is necessary to refresh the browser window to upload the web page again.
