• Time Synchronization-B (DM-TS-B)
• UTCTimeSynchronization-B (DM-UTC-B)
• For more information, please contact producer.

CANopen unit

• CANopen unit consists of Master and Slave communication ports. They are independent, thus can be connected to two different CAN network at the same time.
• The ports can operate at baud rates 50 kbps, 125 kbps or 250 kbps.
• It follows the internationally standardized (EN 50325-4) CAN-based higher-layer protocol for embedded control systems. Advised rules and concepts by this standard must be followed to fulfil the conditions and so achieving normal operation and results.
• The structure of the network as cable type and lengths, baud rates, number of the nodes and termination must be taken into account within the recommendations and requirements, when designing the network.
• The bus network can consist of at least one Master and at list one Slave node by the standard, but it is advised that with increased number of nodes, the Master node fastest interval is extended. Below are two examples:
• Example 1: network with 1 master and 9 slaves, every slave have defined 32 (4×8) byte of data and baud rate 125 Kbps. Fastest Cycle time for this configuration is 50 ms.
• Example 2: network with 1 master and 4 slaves, every slave have defined 4 byte of data and baud rate 250 Kbps. Fastest Cycle time for this configuration is 5 ms. 5 ms is the fastest recommended cycle time.
• It is recommended to power-up all the nodes on the same network at the same time, if some or all nodes had been reprogrammed (to reinitialize the communication properly).

RUN/STOP Switch

• Run: Status RUN status LED “on” indicate that the user graphical application is up and user program is running.
• Stop: When the switch is turn to STOP state, the RUN status LED is “off” and application is stopped.

PLC task cycle time

• Main PLC task interval (under Project tab -> Resource Tasks Interval) time → → is not recommended to be set lower than 50 ms.

GUI design and programming

NOTE: Recommended minimum size of the touch object is 10 x 10 mm.

1. Configuration of the PLC is done using Smarteh IDE software tool. Please refer to LPC Manager user manual for details.
2. Configuration of the PLC is done using Inkscape open source tool.
