94/316 Bosch Rexroth AG | Tightening Technology 7 Data Services7.2 Ethernet communicationFormats for floating decimal numbersMeasurement results and limits for torque, angle, and gradient are shown as floating decimal numberswith a varying number of digits. The decimal character is output as a decimal point. The number of digitsbefore and after the decimal point are:Table 7–5: Number of digits before and after the decimal point for measurement valuesMeasurement/limit valuesNumber of digits beforedecimal pointNumber of digits after decimalpointTorque 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 2ExampleESA065G hand-held nutrunner with maximum allowable output torque of 65 Nm. The set and actualtorque values are indicated with two digits before and after the decimal point, e.g. _4.00 or 16.23 oralso _0.17.Illustration of tightening channel numbersIn the Tightening System 350, channel numbers are always indicated with a card rack number and a cardslot number. The channel number is always “0.1” for the CS351 Compact System.Descriptions for switch-off criteria (SB)The switch-off criteria describe the reason why a tightening was stopped. This information is an importantaid for analyzing tightening processes.Output is in the SB (stopped by) format + indexExampleSB 3 means that the tightening process was stopped by the target function Torque.Table 7–6: List of switch-off criteriaIndex Process stopped by tightening controller01 Unknown abort2 Target function General3 Target function Torque4 Target function Angle5 Target function Time6 Target function Yield pointSystem 350 | 3 608 878 040/05.2008
