1MRS750881-MUM REC 52339Remote Monitoring and Control UnitTechnical Reference ManualEach change (rising or falling edge) detected in the status of a digital input is time-tagged at an accuracy of ±1 ms. The time tag represents the moment (time) of thelatest input change of the value attribute. The time is not recorded until the filteringtime of the status change has elapsed, which means that the filtering time does notaffect the time tag value.Count (BI#Count)The count attribute indicates the number of positive input transitions of a filteredinput. The frequency range of a digital input parameterized to operate as a pulsecounter is 0...100 Hz. If a digital input is changed into a pulse counter, the attributeBI# is frozen at the value valid at the moment of the change.The example below shows how the attributes of the digital input 1 (PSC_7_BI1 onPSC1 module) of REC 523 are named for the configuration:PSC_7_BI1IV; digital input invalidityPSC_7_BI1; digital input valuePSC_7_BI1Time; time tagPSC_7_BT1Count; counter value5.5. Digital outputs5.5.1. GeneralThe outputs of REC 523 are categorized as follows:ï HSPO High-speed power output, double-pole contact.ï SO Signal output, either NO (Normally Open) or NO/NC (Normally Open/Normally Closed) contact.The events and parameters of I/O cards can be found in the event and parameter listson the CD-ROM Technical Descriptions of Functions (refer to Section 1.8. Relateddocuments).For detailed information about terminal connections for the outputs, please refer tothe terminal diagrams, where all the outputs and relay connector terminals arepresented.Table 5.5.1-1 REC 523 digital outputsREC 523Outputs PSC_7_HSPO1PSC_7_HSPO2PSC_7_SO1 (Heater output)BIO1_3_SO1BIO1_3_SO2BIO1_3_SO3BIO1_3_SO4BIO1_3_SO5BIO1_3_SO6Outputs / total 9
