Introduction

The communication module AS00SCM-A in remote mode (RTU) plus communication card AS-FCOPM, allows the use together with equipment of other series (Ex .: DVP) and with third-party devices that work with CANopen (DS301). When using the Delta PLC as a CPU, you must use the CANopen Builder to configure the network and perform mappings of equipment on the network.

Note: An AS CPU will always be required to configure the SCM before use.

Settings

When the AS-FCOPM communication card works with the AS series PLC, it supports three types of modes (RTU) remote terminal unit: “AS Remote Communication”, “CANopen DS301 Mode" and "Delta Special Driver & AS Remote Mode”. Use the FORMAT1 key to select between the three modes (RTU) remote terminal unit.

THE. FORMAT 1: Communication mode configuration (RTU) selection key.

B. ID1 / ID2: Address setting selection key (network ID).

• ID1: (0 ~ F) recommended to leave equal to "0".
• ID2: (0 ~ F) address of the slave.

Ç. FORMAT2: Communication speed selection switch (RTU).

D. (COM) mode: The AS00SCM-A will function as a communication module and will be powered by the CPU bus.

Mode (RTU): The AS00SCM-A will function as a remote unit and must be detached from the CPU and independently powered.

Hardware Identification and Configuration

Before using the AS00SCM-A module as a remote I / O unit (RIO), the module configurations must be downloaded with the aid of an AS CPU. To do this, follow the steps below.

3. With AS00SCM-A decoupled from the AS CPU, set the selection keys: ID1 = 0, FORMAT1 = 0 (AS Remote Communication), ID2 = 1 (address) and FORMAT2 = 7 (1000kbps).
4. Connect the CANopen cables between the AS00SCM-A and the AS CPU, fit the I / O modules, change the switch to RTU mode and power the module.
5. Open ISPSoft (V3.11 or higher) and adjust the hardware settings in HWCONFIG.
6. Within HWCONFIG, if it is the first time you are configuring the CPU, do the Scan, otherwise do the Upload of the CPU settings, as the Scan overwrites all previous settings.
7. Double click on the CPU to open the editing area.
8. Access the menu Function Card 2 Setting.
9. Within the menu, adjust AS-FCOPM Working mode: AS Remote Communication. This will be the communication mode for downloading the module configurations.
10. Adjustment AS Remote module No. with the quantity AS00SCM-A that will be working in RTU mode on the same CANopen network. In the case of the example it will be 1.
11. Adjust the communication speed in AS-FCOPM Bit Rate according to the length of the CANopen network. This value must be the same as that configured in AS00SCM-A. See the FORMAT2 table for more details. In the case of the example, it will be configured as 1000kbps.
12. After that, AS00SCM-A will appear connected to the CPU at HWCONFIG. Add the modules that will be coupled using the product list. If you add an I / O module that does not exist in the AS00SCM-A, it will have an error.
13. Download the settings.
14. At this time, the CPU and AS00SCM-A will be communicating through the mode AS Remote Communication.
15. To work on the CANopen DS301 network, now set the selection keys: ID1 = 0, FORMAT1 = 4 (DS301), ID2 = 2 (address) and FORMAT2 = 7 (1000kbps). Note: The address must be greater than 1 because, by default, the address of the CPU AS-FCOPM card is 1 (AS-FCOPM node ID).
16. After adjusting the selection switches, the AS00SCM-A must be turned off and on for the settings to be accepted.
17. Now inside HWCONFIG, adjust AS-FCOPM Working mode: DS301 and keep the configured value in AS-FCOPM Bit Rate.

If after the steps above the AS00SCM-A error LED is blinking, redo the steps above, as it is likely that some I / O module has been configured incorrectly or is not attached.

Configuring the CANopen Builder

1. Within HWCONFIG, right-click the AS-FCOPM CPU card to access the menu.

2. Open CANopen Builder (AS-FCOPM).

3. Within CANopen Builder, go online and scan the network. AS00SCM-A will appear with ID2.

4. Right-click on the AS00SCM-A and open the properties to map the PDOs of the modules' I / Os.

5. Within the properties of the AS00SCM-A, add the PDOs according to the desired function and map the PDOs for each module.

6. Then double-click on the CPU to open the properties.

7. Within the properties, transfer the available nodes (Available Nodes) for the node list (Node List). All RFQs will be directed to sequential addresses.

8. Once mapped, download the new configuration.

9. Now you can read and write PLC programming logic using the mapped addresses.

This same procedure can be done to add other equipment on the network. At the CANopen Builder it is also possible to import EDS files from other manufacturers.
