Functions (continued) 0 Twido programmable controller 0 TwidoSuite programming software Position control, processing, PID Position control Twido compact (TWD LCAp 40DRF), modular and Extreme controllers offer two software positioning functions (frequency 7 kHz) (1) which can be used, for example, for controlling stepper motors: b PLS (pulse) function - pulse generator output b PWM function - pulse width modulation output. This function can also be used for applications with light or sound intensity control (dimmer or volume control function). Constant on to off ratio Variable on to off ratio Variable T period Constant T period PLS function (pulse, 7 kHz) (1) The PLS function block generates pulses of xed ratio. In some cases, the frequency can be xed and in others it is variable (as in control of slopes when driving a stepper motor). The %PLS function block can be programmed to generate a speci c number of pulses. %PLS function blocks are assigned to outputs %Q0.0.0 or %Q0.0.1 on Twido base controllers. The pulse generator signal has a variable period, but with a constant duty cycle which establishes an ON to OFF ratio of 50% of the period (see illustration opposite). PWM function (7 kHz) (1) The PWM function block generates pulses of xed frequency, with a variable ratio between the high state and low state of the output signal. The ON to OFF duration ratio is a dynamic variable called %PWM.R, with a range from 0% to 100%. PWM function blocks are assigned to outputs %Q0.0.0 or %Q0.00.1 on a base controller. The PWM function can be used to control analog module outputs. The user-de ned %PWM function block generates a signal on output %Q0.0.0 or %Q0.0.1 of Twido base controllers (see illustration opposite). Event processing b Event management by the application. b 2 priority levels b 3 types of source: v 4 event sources based on the basic inputs v 4 event sources based on the very fast threshold counter (VF counter) v 1 event source based on the periodic event (Timer) b Command masked and enabled by the system bits b Each event executes a single user logic subroutine b Updating of “re ex” outputs PID b 14 PID programming loops b “Autotuning” algorithm (for software version u 2.5). b Analog/PWM output b Linear conversion of measuring input b 2 alarm levels (high and low) on the “measurement” b Command output limits b Direct and inverse action b 2 animated modes for PID: con guration mode, debug mode Online modification This application can be debugged and adjusted in online mode. With this mode, the application program contained in the PC memory is identical to that in the controller memory. Program modi cations can therefore be made directly in the Twido controller.
