MMTCP16DI - DIGITAL INPUTS WITH COUNTERS

The MMTCP16DI module is a 16 channel digital input module. The inputs are isolated from the logic by bi-directional opto-couplers. The inputs are divided into 2 isolated groups of 8 inputs each. This allows for many configurations in which the input module may be used. One such configuration could be where one group is connected as common positive and the second group connected as common negative.

The counters operate in three modes.

In mode 0 all the counters are disabled.

In mode 1 the first eight inputs (1-8) have internal counters associated with them. These counters are 32 bit counters allowing a count value from 0 to 4294967295. The count value can be cleared by writing a zero to the associated registers or preset to any other value using the same method.

In mode 2 the inputs are connected as up/down counters. Input 1 will increment counter 1 whilst input 2 decrements counter1. In the same way, inputs 3&4 operate counter 2, inputs 5&6 operate counter 3 and inputs 7&8 operate counter 4.

Note: The count values are not battery backed-up and will be lost if power is turned off.

The format of the registers allows the status of the inputs to be read as either single bits or all at once as a single register on the Modbus network.

Each MMTCP16DI Module has a unique Ethernet IP address which must be programmed into the PC or PLC. The IP address in the MMTCP16DI 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.

The web page address for viewing the digital input status parameters is http://169.254.111.111/index.htm and the address for viewing the counters is http://169.254.111.111/counters.htm.

WIRING

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.

The Web page address "169.254.111.111/countcfg.htm" is entered into the address line of the browser window to access the counter configuration page. This page allows you to enter a Counter Description Name for identification/maintenance purposes.

	Counter Names: These fields allow you to enter a counter description name into the MOD-MUX TCP Module. This is an identifier for diagnostic/maintenance purposes and is chosen to best describe the particular counter 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.
	State: This is the current state of the inputs. To get an updated reading it is necessary to refresh the browser window to upload the web page again.

To view the Counter Web page in the MOD-MUX TCP Module, start the Web browser and type "169.254.111.111/counter.htm" into the address line of the browser window.

	Counter: This refers to the actual input number on the terminals of the module.
	Counter Name: This is the name that was entered in the configuration page to best describe the counters.
	Count: This is the current count on the inputs. To get an updated reading it is necessary to refresh the browser window to upload the web page again.
	Counter Configuration: This is the mode as described at the beginning of this section.
