5. Counter Registers The counters are stored in two 16 bit registers The first register is the High Register and the second register is the Low Register To get the actual 32 bit count value the registers must be combined as follows Counter High Value Register 40003 Counter Low Value Register 40004 Counter Value Counter High Value X 65535 Counter Low Value 3 2 7 4 Output Watchdog Timer The watchdog timer is used to switch off all of the outputs in the event of a communications failure When set to zero register 40101 the watchdog timer is disabled 3 3 IOX 6RTD RTD INPUTS 3 3 1 Description The IOX 6RTD module is a 6 RTD input module The module can accommodate either 2 or 3 wire RTD sensors The RTD inputs are isolated from the logic The RTD resistance is read by the module circuitry linearised and converted to degrees Centigrade No ranging is required as the module covers the full range of the RTD as indicated in the RTD table The value that is read from the Modbus register is the actual temperature in degrees centigrade to 0 1 C resolution ie a value of 3451 corresponds to a temperature of 345 1 C The RTD type is setup by writing a value to the RTD Type register The value is obtained from the table below For example to select a PT100 RTD the value 1 must be written to the RTD Type register All 6 RTD inputs adopt the same RTD type The DIP switch 9 is used to select upscale or downscale burnout
