Communication Capabilities 1 |
1.2Dedicated Protocol Communication
The α2 (AL2-14MR-*, AL2-24MR-*) Series Controller can transfer data To/From a personal computer, HMI, or other peripheral equipment via Dedicated Protocol. Programs for Dedicated Protocol can be written in C++. Visual Basic, or similar high-level programming languages.
Please see the information in Chapters 5-8 for more information on Dedicated Protocol.
1.2.1Dedicated Protocol Configuration
The peripheral equipment acts as the Master in the Dedicated Protocol configuration. The communication takes place via a 1:1 RS-232C communication link.

1.2.2Diagram for RS-232C Cross Cable
The pinouts and connector types for the RS-232C cross cable are shown in the figure below. Both the connectors and the wiring are equivalent so that either side can be connected to the AL2-GSM-CAB or the peripheral device.
