Measurement / Control via MscDll
Example "position-triggered dynamic measurement"
Preliminary considerations
Based on the resolution of the incremental encoder of 3600
increments / rotation and the step-size of 0,5°, the step-size
between two samples is 5 increments.
Example-Code
// Write channel list 1 using the measurement channels T4 and
T5
ansiString = “#1;T4;T5# ”;
WriteCommandStr(opcWCL, ansiString);
if (ansiString != “ #0# ”) return -1; // An error occured: cancel
starting measurement
// Define trigger:
// TriggerNo 1; position-triggered; trigger-channel =
measurement channel T12; divisor = 1;
// step-size = 5; start = 0; end: * = without end
ansiString = “ #1;P;T12;1;5;0;*# ”;
WriteCommandStr(opcDT, ansiString);
if (ansiString != “ #0# ”) return -2; // An error occured: cancel
starting measurement
// Define dynamic measurement 1:
// TriggerNo 1; channel list 1; dyn. measurement active; 720
measurement values
ansiString = “ #1;1;1;720# ”;
WriteCommandStr(opcDDM1, ansiString);
if (ansiString != “ #0# ”) return -3; // An error occured: cancel
starting measurement
// Setup data transfer channel for dynamic measurement values
result = MSC_SetupExtendedDynamicChannel(pDevice, opcRDM1, 2,
1, NULL);
if (result != MSC_STATUS_SUCCESS) return -4;
// Allocate 2 buffers, each having a size of 720 * 4 Bytes =
