Communication by the Modbus TCP/IP
protocol with Quido
See also Communication with meters by the Papouch company (Czechia)
The valid TCP-IP
address must be set for the device according to the corresponding network environment. The configuration is described in the documentation supplied by the manufacturer.
This preconfiguration can be activated when creating a new object (e.g. by "New object ..."
in the local object menu or by pressing the Insert
key after selecting the object) and is included in the group: "/ Communication / Protocols and other communications / Modbus"
This preconfiguration can be created in the object: PmaFolder
- The preconfiguration is created including the panel (object of the PmaPanel
type) is functional also a Web panel
- The panel is used for communication testing and it is not essential for the communication functionality.
In the PmaComm
object named "Comm
" the communication parameters are set (Network address
object named "data
" includes a "Parameters
" tab where Special Parameters
are defined (see PmModbusMr - Driver for communication by the Modbus Master protocol
). On the "Data"
tab, the items are imported by data extension of items defined in the PmaData
object (see ExtComm
If the "Temperature sensor connected
" configurator was checked in the preconfiguration, then there will be the temperature meter present in the right part of the panel. In the left part of the panel there are two columns with PmgBox
objects. These objects contain identical dinx
parameter. The parameter specifies the index (order) for connection the Pmg
objects to the correct data, independently for DI and DO. The inserted objects display according to their purpose, the values, names and color status based on the data comming from the communication. The column for digital outputs also contains two ON/OFF buttons that can be used for controlling the digital outputs.
These configurators can be set before the preconfiguration is created:
|The name of created object||Name of the object created in the tree of Pma objects. The maximum name length is 30 characters. This is a system name, so it must contain only alphanumeric and must not contain any diacritics (i.e. national dependent chars), empty string, spaces and the first character must not be a number.
|Temperature sensor connected||If the connected I/O module supports temperature measurement and the temperature sensor is connected|
|Number of binary inputs||The number of binary inputs of the connected module|
|Number of controlled binary inputs||The number of binary inputs of the connected module|
|Network address||Network address to which the communication will be connected.
The address can be entered by both IPv4 address (e.g. 192.168.0.15) or by computer name (e.g. server11).
The IPv4 address 127.0.0.1 is the local address of this computer.
Macro expression can be used for input (it is evaluated after starting the application).
After the preconfiguration is created, the "PmaComm > Setting the parameters of the Ethernet-client > Network address" configurator will be set to this value.
|Close the connection after each transmission||This option sets the following configurators simultaneously:
Not connect until first transfer. See: PmaComm > Setting the parameters of the Ethernet-client > Not connect until first transfer
Close connection after every transfer. See: PmaComm > Setting the parameters of the Ethernet-client > Close connection after every transfer
|Communication refresh rate [ms]||The period in milliseconds to be used for reading the current data by the PROMOTIC application.
After the preconfiguration is created, the "PmaCommGroup > Parameters > Communication refresh rate [ms]" configurator will be set to this value.
