Support

It should use MODRW instruction to write or read the data via modbus communication.

Firstly we need to check the error code in Auto Station(PLC info), and take measures mentioned in the manual for each error code, if necessary, we can try to format PLC.

IVC1L, IVC2 and IVC3 series PLC can support, but IVC1S cannot support this function.

It can set 4x700=1 to save the value or use the retained registers in HMI.

Sometimes it can read the value of data(6041h bit10), but sometimes it cannot, what can be the reason?
Modify the CANopen settings in PLC: change send PDO as synchronous, receive PDO as asynchronous, and heartbeat time sets as 0 or 200ms above(this value cannot set too small).

It can use DROL instruction in PLC to move 16bit, and then get and minus value.

It can use special relay to monitor the status(busy is ON, ready is OFF); And SM82, SM82 are corresponding with Y0 and Y1.

IVC2 only supports 2 channels of 100kHz high speed pulse input, and 3 channels of 100kHz high speed pulse output; IVC3 supports 8 channels of 200kHz for both high speed pulse input and output;

The most economic series of our PLC is IVC1S series, and its main features are:

1, it supports 6 channels of 10kHz high speed pulse input, and 2 channels of 100kHz high speed pulse output;

2, it supports 1 channel of RS485 and 1 channel of RS232;

3, it doesn't support extension module and can support maximum 60 IO;

4, it doesn't support real-time clock function.
