Module of PLC, DCS, ESD system card, the card is a vibration monitoring system, steam turbine control system module, the advantages of the gas generator spare parts brand: Allen Bradley, BentlyNevada, ABB, Emerson Ovation, Honeywell DCS, Rockwell ICS Triplex, FOXBORO, Schneider PLC, GE Fanuc, Motorola, HIMA, TRICONEX, Prosoft etc. Various kinds of imported industrial parts of our products are widely used in metallurgy, petroleum, glass, aluminum manufacturing, petrochemical industry, coal mine, papermaking, printing, textile printing and dyeing, mechanical, electronic manufacturing, automobile manufacturing, plastic machinery, electric power, water conservancy, water treatment/environmental protection, boiler heating, energy, power transmission and distribution and so on.
Analog Reads (Input Registers) Input registers are analog values that are readable from, but not writable to, the 505E control. An example of an analog read value would be turbine speed. The values of the input registers are stored internal to the control as floating point numbers representing engineering units (i.e. KPA or RPM). The values that are transmitted are integer values ranging from -32767 to +32767. Since Modbus can only handle integers, values that require a decimal point must be multiplied by a scaling constant in the 505E before being sent across the Modbus link. For example, these input registers may be listed as the Modbus value ‘x100’ or ‘cascade scale factor’ under the description heading to denote the value is multiplied by a scaling constant (refer to Modbus Scale Factors later in this section). This will allow transmission of decimal parts of a unit if this is necessary for better resolution. See the 505E Service mode for defaulted communication constants and ranges. The 505E control supports Modbus function code 4, which involves reading selected input registers. The input registers available are listed in Table 6-7.
Analog Writes (Holding Registers) Holding registers are analog values that are writable to the 505E control. These values can also be read from by a device performing error checking. An example of an analog write value would be a direct speed setpoint value as opposed to raise and lower setpoint commands. The value of the holding registers are also stored in the control as numbers representing engineering units (i.e. PSI or RPM). Once again, if decimal points are required, a scaling factor must be used (refer to Modbus Scale Factors later in this section). The 505E control supports Modbus function codes 3, 6, and 16. These correspond to reading selected holding registers, writing to a single holding register, and writing to multiple holding registers, respectively. The holding registers available are listed in Table 6-8. The following tables give the address and description of all Boolean and analog, reads and writes.
