CP 341 MODBUS DRIVER
If bit cp 341 modbus 6 the bit to the right of the most significant bit is set, the send job refers to bit registers. Bit 2 6 doesn t affect the function code actually sent, it is just information for the master CP for what to expect in the response from the slave when reading cp 341 modbus what to send when writing.
The register s accessed in the slave when bit 2 6 is set must be within a bit register address range defined in the slave such that 4 bytes per register is returned in the read response or 4 bytes per register are expected in a write request. If bit 2 6 is set and a normal 2 bytes per register range is read in the slave, 2 cp 341 modbus per register is returned by the slave.
As the master expects more data, the activated send job is finished with error. Likewise, bit 2 6 is cp 341 modbus set and a 4 bytes per register range is read in the slave, 4 bytes per register is returned by the slave.
The master receives more data than expected and the activated send job is finished with error. If bit 2 6 is set and a normal cp 341 modbus bytes per register range is written to the cp 341 modbus, 4 bytes per register are sent by the master and the slave should returned an exception response to the master.
Likewise, if bit 2 6 is not set and a 4 bytes per register range is written to the slave, 2 bytes per register are sent by the master and the slave should returned an exception response to the master. The parameter bit start address cp 341 modbus not checked by the driver and is sent unchanged.
Any value between 1 and is permitted as the amount of bits number of coils. The cp 341 modbus received byte is entered as the Low Byte of the 1st word data, the 2 nd received byte is entered as the High Byte of the 1 st word data, and the 3rd received byte as the Low Byte of the cp 341 modbus word data, etc. If an odd number of bytes are returned, the value 00H is entered into the High Byte of the last word. Any unaccessed bits in the last received byte are masked to zero in the destination byte regardless of the received value.
Any cp 341 modbus bits in the last received byte are masked to zero in the destination byte regardless of the received value MLC — Special offer. Hope this helps, Daniel Chartier.
