AMiT Communication Driver

AMiT Communication Driver is intended for data connection between Reliance's runtime software and control systems manufactured by the AMiT company.

AMiT devices can be connected to a PC in the following ways

DOKOPO communication card
COM port
Modem
Ethernet (UDP protocol)

Supported Reliance versions

The communication driver is supported in both Reliance 5 and Reliance 4.

Reliance supports reading and writing the following tag types

Bool
Integer (16 bits, integer with a sign)
LongInt (32 bits, integer with a sign)
Float (32 bits, number with a floating point, single precision)
Integer matrix
LongInt matrix
Float matrix

In the Reliance project, these data types correspond to the matrices

Array of Integer
Array of LongInt
Array of Float

The driver converts the matrices into one-dimensional arrays so that the row index increases before the column index. This means that, for example, a matrix named "M" 2 by 2 elements is converted into a four-element array as follows: M(1,1); M(2,1); M(1,2); M(2,2), where the first index indicates the row while the second indicates the column of the matrix element.

AMiT control systems

SW requirements

For communication, the driver uses an ActiveX control (the AtouchApp object) that is part of AMiT's AtouchX object library. First, it is necessary to install this library so the driver works properly. The AtouchX library installer is available in the directory Drivers\AMiT\AtouchX\ on the Reliance installation CD and in the directory <Reliance>\SupportFiles\Drivers\AMiT\ (<Reliance> is a directory where the Reliance software is installed).
