Page 22: Slice I/O Terminal Introduction
Section 1-1 Slice I/O Terminal Introduction Slice I/O Terminal Introduction A Slice I/O Terminal is a building-block style remote I/O terminal made up of a Communications Unit and a number of Slice I/O Units, which each provide a small number of I/O points. The Slice I/O Units communicate with the host by remote I/O communications (cyclic communications) through the Communica- tions Unit.
Page 23 Section 1-1 Slice I/O Terminal Introduction Parameter Backup and Before replacing a Slice I/O Unit for maintenance, the parameter data set in Restore the I/O Unit can be backed up in the connected Communications Unit. The backed up parameter data is compared with the replacement I/O Unit’s data and the backed up data is restored to the replacement I/O Unit.
Page 24 Section 1-1 Slice I/O Terminal Introduction Contact Operation This function can count the number of times each input or output contact Counter changes from OFF to ON (maximum resolution: 50 Hz). A warning set value can be set in the Unit to monitor the number of contact operations, and turn ON a warning flag in the Status Area when the set value is reached.
Page 25 Section 1-1 Slice I/O Terminal Introduction The status can be checked at the Master using the Off-wire Detection Flag. This function is valid only for the input ranges 4 to 20 mA and 1 to 5 V. User Adjustment Input or output values can be adjusted to compensate for errors in the input or output voltage or current resulting from the characteristics or connection methods of the I/O device.
Page 26 Section 1-1 Slice I/O Terminal Introduction Temperature Zone The temperature zone counter can be used to measure how long the temper- Counter ature input value is within a user-set temperature range in 1-second incre- ments. The host will be notified with a flag when the measured value exceeds the set value.
