505E Controlling Parameters The controlling parameter status of the 505E uses two Analog Read registers (3:0070) & (3:0071) to identify the two parameters that are in control of the 505E. The analog register (3:0070) corresponds to the top line of the display. Analog register (3:0071) corresponds to the second line of the display. These variables follow what is displayed on the controlling parameter screen, under the ‘CONT’ key. The variables gives the current status of the control and is defined in the following table.
Specific Address Information Entering Setpoint from the Modbus The setpoints for the Speed, Extraction, Cascade and Auxiliary can be entered through the Modbus link. When the setpoint is entered for any of these functions the setpoint will not move instantly, but the setpoint will move towards the entered setpoint at the ‘entered rate’ defined for the function in the program mode (see Direct Setpoint Entry information in Chapters 3 and 5). The direct setpoint entry from Modbus functions the same as entering the setpoint from the front panel of the control. Manual 85018V1 505E Digital Governor Woodward 199 There is feedback provided to let the operator know what value was entered. This value will not change until a new value is entered from the Modbus. The addresses, 3:0060- :0063, are for speed, cascade, auxiliary, and extraction/admission respectively. When the a new value is entered from the Modbus, the setpoint will move to the new value. If the entered setpoint that is the same as the feedback, the operator can use a ‘Go To Modbus Entered’ setpoint command (0:0017, 0:0029, 0:0037, & 0:0063) instead of entering the setpoint again. This command needs to be used when the setpoint to be entered is the same as the feedback. Modbus Scale Factors Modbus has two limitations: • only integers can be sent across; • the value is limited between -32768 and 32767. These limitations can be overcome by scaling the value before it is sent across the Modbus. The default scale factor for the analog values is 1. The scale factor can be changed in the Service Mode between 1 and 100. The following input and setpoint values that are sent across the Modbus have independent scale factors: Casc (3:0030), Aux (3:0037), FSP (3:0041), KW (3:0045), Sync/Load Share (3:0043), and Extr/Adm (3:0056). These scaled parameters and their scale factor are available through the Modbus. Values that require a decimal point must be multiplied by the scale factor (10, 100) prior to being sent across the Modbus. The value sent must then be divided by the scale factor in the Master. The Scale Factor adjusts all associated analog reads and writes accordingly. For example, the Cascade Scale Factor adjusts the cascade input and setpoint analog read values as well as the Entered Setpt analog write value. For example, if the Cascade setpoint of 60.15 needs to be sent across the Modbus and have two decimal places, the Cascade Scale Factor would be set to 100 in the Service Mode. This will change the value so that the decimal places can be sent across the Modbus communications link (60.15 * 100 = 6015). After the value is sent across the Modbus, it must be rescaled in the Master to the original value (6015 / 100 = 60.15). A Directly Entered Cascade Setpoint (4:0002) of 61.5 would be sent across the link as 6150 and the 505E automatically divides the value by the Casc Scale Factor and uses the value of 61.5 as the setpoint desired.
