[. . . ] Up to that point, the actuator will stay in the defined safety position [nciDefaultOutput]. Watchdog-timer in case of manual operation. Is the actuator working in the manual operation mode (nviManActPos INVALID) the watchdog-timer is working in the background. This means, if the controller fails, the watchdog-timer expires and after switching manual operation [nviManActPos] to [INVALID] the actuator is running to the safety position according to the definition in [nciDefaultOutput]. 0% FACTORY SETTINGS State of the Network and Configuration Parameters: nviActPos = 163. 835 (INVALID) nviManActPos = 163. 835 (INVALID) nviActPosFb = 163. 835 (INVALID) nvoDIswitch = [ 0. 0 -1 ] after initialization (3 sec. ) = [ 0. 0 0 ] (if there is no switch connected) nciDefaultOutput = 163. 835 (INVALID) nciDirRev = 1111111111111111 (for M7410G1008 / -16 / -24) nciDirRev = 100000000000000 (for M7410G1032 / -40 / -57) nciMaxRcvTime = 0. 0 sec nciDIconfig = ST_OFF nciRunTime = 6553. 5 (INVALID) 100 % INTERRUPTION OF THE SYNCHRONIZATION The interruption of the synchronization after Power-on / Reset (nciDefaultOutput = 0 or 100 %) is not possible. Later synchronizations can be interrupted every time. 11 EN0B-0235 GE51R0802 PRODUCT DATA WHAT HAPPENS AT OFFLINE-ONLINE MODE CHANGES If the actuator is taken offline by a network management tool the application program of the device stops, and the following actions will be done before the offline mode takes place: Online-Offline change · The motor stops, if it is running · The Status LED is taken off · The network variable nviActPosFb will be set to INVALID (163. 835), to show that the actuator is in a undefined situation · The state-value of the network variable nviDIswitch will be set to INVALID (255 = 0xFF = -1), to show that the actuator is in a undefined situation. Offline-Online change · Application restart. Same situation as Power-on or Reset. EN0B-0235 GE51R0802 12 PRODUCT DATA CONTROLLER OBJECT (ACTUATORS WITH PI-CONTROLLER ONLY) The controller object supports the following network variables used for the communication and configuration Controller Object Controller Object, Object Type 5 nviActualTemp SNVT_temp_p nvoValvePosition SNVT_lev_percent nv1 nv7 nv2 nviSetpoint SNVT_temp_p nv3 nviSetPtOffset SNVT_temp_p Network Variables nv4 nviEnergyHoldOff SNVT_switch nv5 nviOccupancy SNVT_occupancy nv5 nviApplicMode SNVT_hvac_mode Configuration Parameter nc 78 UCPT UCPT nciSetpoint nciPIGains[2] nciPIGains. pi_Xp nciPIGains. pi_Tn nciPIConfig (SNVT_temp_p) (SNVT_temp_p) (SNVT_time_sec) (Heat / Cool) Optional Configuration Properties Modify SCPT´s anytime (no reset of device) Fig. 12 Controller Object 13 EN0B-0235 GE51R0802 PRODUCT DATA DESCRIPTION OF USED SNVTS AND SCPTS This table shows all used standard network variables and standard configuration parameters, their default values, a short description, the range and the send conditions and service of the outputs. Standard Network Variable Type {Range} {factory settings} Network Variables nviActualTemp SNVT_temp_p {-163, 80 to 163, 80; 327, 67} {327, 67} = INVALID Definition nviActualTemp = 327, 67 [INVALID] after Power on or Reset. If nviActualTemp is INVALID than nvoValvePosition will be Invalid, too, cause no control loop is possible. not equal 327, 67 [INVALID] normal operation If nviActualTemp is not INVALID than normal operation is possible. Explanation nviActualTemp includes the actual temperature delivered by an separate LON temperature sensor. Received values below ­163, 80°C are calculated like ­163, 80°C and values above 163, 80°C will be calculated with 163, 80°C. The only exception is the value 327, 67 = [INVALID]. Is this value received, the output of the controller nvoValvePosition will be set to INVALID, too. Received values below ­157, 80°C are calculated like ­157, 80°C and values above 157, 80°C will be calculated with 157, 80°C. The only exception is the value 327, 67 = [INVALID]. Is this value received, the internally setpoint [nciSetpoint] will be taken as the actual one. If the SNVT nviSetPtOffset is not INVALID than the required temperature will be evaluated like this. Setpoint = nviSetpoint + nviSetPtOffset nviSetPtOffset works together with nviSetpoint or nciSetpoint and is part of the actual required temperature. Received values below ­157, 80°C are calculated like ­157, 80°C and values above 157, 80°C will be calculated with 157, 80°C. The only exception is the value 327, 67 = [INVALID]. Is this value received, it will be ignored. Can be used for binding of a physical digital input, e. g. nvoDIswitch from the internal actuator object. So the energy could be saved if an open window or a dewpoint sensor detects a situation to switch off the energy = close the valve totally. This means no more heating in HEATING applications or no more cooling in COOLING applications For binding of an occupancy sensor.
