The following text describes the possible communication options of the PROMOTIC system with PLC devices and IO modules by the
).
Communication via the AtouchX activeX object

This document amends the trade-technical information to the
AMiT AtouchX communication drivers. The complex information to the
AtouchX driver is provided by the
AMiT company.
The communication with the
AMiT HW (
Amiris,
Adis, etc.) can be carried out by methods:
- serial link RS232 or RS485
- Phone modem (up to 255 subscribers, Amit HW can also dial telephone numbers)
- LAN network (Ethernet) - checked that it is 5-times quicker than over the RS485 with the 38400 Bd speed rate.
All 4 types of the connection are supported by only one
AtouchX communication driver that was developed by the
AMiT company. The
AtouchX is supplied as the
ActiveX object.
The PROMOTIC system accesses the AtouchX driver by the PmaActiveX object. This object accesses calling the AtouchX methods and captures its events.
- For easy integration of this driver into the application it is handy to use:
Trade terms:
The AtouchX is available on the https://amitomation.cz, where free download is possible.
The usage of the PmaActiveX object requires purchase of the "PmActiveX" licence. With the freeware version PmFree, or when developing the application (with development environment for tersting purposes), this component is always functional.
Communication with the IO modules by the AMiT company
For example the following modules:
DMM-DI24,
DMM-DO18,
DMM-AI12,
DMM-AO8,
DMM-RDO12,
DMM-PDO6NI6,
DMM-UI8(R)DO8,
DMM-UI8(R)AO8U,
DMM-FCx.
The remote I/O modules by the AMiT company can be accessed from the PROMOTIC system by two ways:
- With the modules of the
DMM-xx line it is possible to communicate by the
Modbus protocol
RTU. For this communication in the PROMOTIC system can be used:
PmModbusMr - Driver for communication by the Modbus Master protocol.
- For easy integration of this driver into the application it is handy to use:
- For this driver, it is recommended to set the configurators:
-
"Data item address" then enter as follows:
- The digital inputs (DI) usually start at address 0 and are in the area "Bi = Input bits".
- The digital outputs (DO) usually start at address 0 and are in the area "Bo = Coil/output bits".
- Analog inputs (AI) usually start at address 0 and are in the area "Ri = Input registers".
- The digital input counters usually start at address 0 and are in the area "Ro = Holding/output registers".
- For communication of the PROMOTIC application with the modules of the
DMM-xx line by the
ARION protocol the
AMiT company provides the
ArionX activeX object. This object can be used in the PROMOTIC system.
We strongly recommend using the communication by the Modbus protocol, because the ArionX activeX object interface is quite comlicated.
