CP1 Function Block For Reading SX Inverter Operation/Status Parameter Via RS485


SX inverter: View Operation/Status (700)
Name SX_OperationStatus
 
Basic Function CP1 Function Block for RS485 communication with a SX inverter.
Symbol  
Authors OEE-N RE, OEE-HQ HvB
File Name SX_OperationStatus.cxf
Applicable models CP1L-M, CP1H or CP1L-L 
Conditions for usage Communication with CP1W-CIF11 or CP1W-CIF12:
PLC port settings Custom (default SX): Baud 9600, format 8,1,N, Serial Gateway.
CIF settings: SW1=ON, SW2=ON, SW3=ON, SW4=OFF, SW5=ON, SW6=ON
Function Description Function Block with parameter Input for viewing all actual operational data, such as actual speed, Torque, Power, Current, Voltage, Frequency and Heat sink temperature.
FB Precautions The SX_OperationStatus function block is offered 'as is' and may serve as a basis for development. Users should previously test its adequacy to the final application.
Omron can not be held responsible in case of malfunction
EN input condition • Connect EN to condition for the FB to Work.
• Start Command send the Request command to the SX and Value output is presented 
   in Floating point format.
 
Restrictions
     Input variables
• CP1 Port number is 1 or 2
• CP1 Model is 0 (CP1L-M / CP1H) or 1 (CP1L-L)
• SX Inverter Node number 1-247
     Output variables • Parameter Output Value in Floating point format.
• Error flag for false Input Variable and Modbus Errors. Modbus Error code in hex.

Output variables

Name Variable name Data type Default Range Description
ENO
(May be omitted.)
ENO BOOL    

1 (ON): FB Operating normally
0 (OFF): FB not operating normally

Busy flag Busy BOOL      
Parameter Read Completed Done BOOL      
Parameter Value Done REAL      
Error flag Error BOOL      
Error code ErrorID WORD     Modbus Error Codes:
0x00:  Normal end Not an error.
0x01: Illegal address. The slave address
specified in the parameter is illegal (248 or
higher)
0x02: Illegal function code. The function code
specified in the parameter is illegal.
0x03: Data length overflow. There are more than
94 data bytes.
0x04: Serial communications mode error. The
Modbus-RTU Easy Master function was
executed when the serial communications
mode was not the Serial Gateway Mode.
0x80: Response timeout. A response was not
received from the Servo.
0x81: Parity error A parity error occurred.
0x82: Framing error A framing error occurred.
0x83: Overrun error An overrun error occurred.
0x84: CRC error A CRC error occurred.
0x85: Incorrect confirmation address. The slave
address in the response is difference from
the one in the request.
0x86: Incorrect confirmation function code. The
function code in the response is difference
from the one in the request.
0x87: Response size overflow. The response
frame is larger than the storage area (92
bytes).
0x88: Exception response. An exception
response was received from the slave.
0x89: Service being executed. A service is
already being executed (reception traffic
congestion).
0x8A: Execution canceled. Executing the service
has been canceled.
0x8F: Other error. Other FINS response code
was received.
