8.2.6. Resources
Group
Resources encompasses a list of hardware and software resources available to
users. Sub-groups hold configurable parameters for Inputs/outputs, asynchronous and
synchronous Timers, Registrator, MT2MT Buffer and Constant parameters.
8.2.6.1. Modbus ID number of module's internal resources
Function - Defines Modbus ID number for internal resources of the
module operating in Modbus Slave mode.
Data type - number
Range - 0....255
Default value - 1
Comments - setting Modbus ID to 0 ( zero ) makes access to internal
module resources impossible
8.2.6.2. Terminals
Sub-group Terminals gathers all inputs and outputs. Depending on type of accepted
input, they are binary and analogue. Final functionality of each input depends on settings
and configuration parameters connected.
8.2.6.2.1. Binary inputs I1,....I8
Module
MT-101 has eight identical Binary inputs. Inputs can operate in one of three
functional modes:
•
Standard binary input
•
counter input
•
analogue input with conversion of frequency to analogue value
Each mode has a set of specific configuration parameters.
8.2.6.2.1.1. Name
Function - Enables entering a friendly input name e.g. connected to the
function performed. The name is displayed on list of terminals.
Data type - text
Range - letters and numerals, max.16 characters
Default
value - Name of resource (I1....I8)
Comments - Using friendly names facilitates recognition of destination and
appropriate settings.
8.2.6.2.1.2. Operating modes
Function - defines operating mode for inputs I1....I8
Data type - selection list
Range - Binary input
the input acts as typical binary input accepting positive and
negative logic.
Analogue input
the input acts as analogue input, measuring frequency of
incoming signal in range from 0....2 kHz.
Counter input
the input acts as counter input. Each pulse appearing on
input increments value of corresponding 32 bit register
