7 Data Services Tightening Technology | Bosch Rexroth AG 149/3167.4 Profibus DP communication7.4.4.2 Arrangement of the results in the output area of the IMpdp interface moduleThe output area of the data buffer in the IMpdp interface module is divided according to the followingscheme:Control signals Single-channel result Single-channel errorContent according to Table 7–34Content according to Table 7–35Figure 7–42:Division of the output area of the data buffer in the IMpdp interface moduleSingle-channel resultThe results storage area contains the single-channel results according to Table 7–34.7.4.4.3 Number format of the result valuesThe measurement results and the limits for torque and angle are generated as floating decimals with avariable number of digits. The number of the “digits before and after the decimal point” are as follows inthe internal display:Table 7–36: Number of digits before and after the decimal point for measurement values (internal floating decimal point display)Measurement/limit valuesNumber of digitsbefore decimalNumber of digitsafter decimalTorque * T MaxSpindle < 10 Nm 1 3T MaxSpindle < 100 Nm 2 2T MaxSpindle < 1000 Nm 3 1T MaxSpindle ≥ 1000 Nm 4 0 (no decimal!)Gradient * T MaxSpindle < 10 Nm 0 4T MaxSpindle < 100 Nm 1 3T MaxSpindle < 1000 Nm 2 2T MaxSpindle ≥ 1000 Nm 3 1Angle A < 10 degrees 1 2A < 100 degrees 2 2A < 1000 degrees 3 2A < 10000 degrees 4 2A < 100000 degrees 5 2Time t < 10 s 1 2t < 100 s 2 2t < 1000 s 3 2t < 10000 s 4 2* The number of digits before and after the decimal point for the torque and gradient depends on the maximumtorque for the tightening spindle.ExampleES065G hand-held nutrunner with maximum permissible output drive torque of 65 Nm. The set and actualvalues for torque are given with 2 digits before the decimal and 2 after, so e.g. _4.00 or 16.23or _0.17.System 350 | 3 608 878 040/05.2008
