Relay Timer Intruduction

Relay Timer is designed as a programmable timer to control relays for industrial usage. The most important thing for timer software is reliable.

It sets the status of relay in batch mode. There are 8 relays in one bank, Relay Timer update the status of all relays in same bank in batch mode. Only 4 bytes of data is transferred.

It keeps updating the status of relays all the time. In case the board lost the connection with the computer, the status of relays will be updated as long as the connection is recovered.

It will back to auto status after 2 hours. It is good that user can control the relays from panel of Relay Timer manually. However, it is bad that user forget to switch it back to auto mode. The Relay Timer will switch back to auto mode automatically after 2 hours of last manual operation.
