MMTCP8DIO - DIGITAL INPUTS / OUTPUTS
The MMTCP8DIO
module is an 8 channel digital input and 8 channel digital output module. The inputs are
isolated from the logic by bi-directional opto-couplers. The common is connected
internally to either the -volts or +volts field power supply terminals using a
jumper link which is situated inside the housing. 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. The 8 digital
outputs are open collector (NPN). The outputs may be used to drive lamps or
external relays when more drive capability is required. The outputs are isolated
from the logic and they share a common negative terminal. When used as a
slave module, the outputs are written to by the Modbus master device such as a
PC or PLC. Each output can be individually switched on or off, or all outputs
can be set up at the same time by writing a single number to the output register
which represents the status of all outputs. Each MMTCP8DIO
Module has a unique Ethernet IP address which must be programmed into the PC or
PLC. The IP address in the MMTCP8DIO 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.
