Example: The parameter is entered in 1/10th of a second. Therefore, if a value of 100 is entered, the command executes no more frequently than every 10 seconds. When the command reaches the top of the command queue and 10 seconds has not elapsed, it is skipped until the poll interval has expired. Register Count 1 to 125 (words) or 1 to 800 (coils) Specifies the number of registers or digital points to be associated with the command. Modbus Function Codes 5 and 6 ignore this field as they only apply to a single data point. For Modbus Function Codes 1, 2 and 15, this parameter sets the number of single bit digital points (inputs or coils) to be associated with the command. For Modbus Function Codes 3, 4 and 16, this parameter sets the number of 16-bit registers to be associated with the command. Swap Code 0,1,2,3 Defines if the data received from the Modbus slave is to be ordered differently than received from the slave device. This parameter is helpful when dealing with floating-point or other multi-register values, as there is no standard method of storage of these data types in slave devices. You can set this parameter to order the register data received in an order useful by other applications. No Change (0)= No change is made in the byte ordering (ABCD = ABCD) Word Swap (1)= The words are swapped (ABCD= CDAB) Word and Byte Swap (2) = The words are swapped, then the bytes in each word are swapped (ABCD=DCBA) Byte Swap (3) = The bytes in each word are swapped (ABCD=BADC) Note: Each pair of characters is a byte. Ex: AB and CD.
Two pairs of characters is 16-bit register Ex: ABCD. Node Address 1 to 255 (0 = broadcast) Specifies the Modbus slave node address on the network to be considered. Most Modbus devices only accept an address in the range of 1 to 247. If you set the value to zero, the command is a broadcast message on the network. The Modbus protocol permits broadcast commands for write operations. Do not use this node address for read operations. Modbus Function 1,2,3,4,5,6,15,16 Specifies the Modbus function to be executed by the command. These function codes are defined in the Modbus protocol. 1 – Read Coil Status (0xxxx) 2 – Read Input Status (1xxxx) 3 – Read Holding Registers (4xxxx) 4 – Read Input Registers (3xxxx) 5 – Force (Write Single) Coil (0xxxx) 6 – Force (Write Single) Holding Register (4xxxx) 15 – Preset (Write) Multiple Coils (0xxxx) 16 – Preset (Write) Multiple Registers (4xxxx)
