2 1. Introduction 1.1 Features Facilitates flexible selection of the control position, offering four different control position settings: remote, local, disabled and logic The control position can be changed via the MMI panel with the R/L key and the logic signals, provided the logic control position setting has been activated via the MMI The control position status information and interlocking bypass status for other application programs Password-protected control position setting 1.2 Application This document specifies the function of the logic control position selector used in products based on the RED 500 Platform. Normally, the device control position setting can be changed via the MMI by choosing the remote, local or disabled position. The function block enables the logic control position as an additional feature. The control position setting can only be changed via the MMI and it allows the control of all objects. In remote position, the control objects can only be controlled via remote communication and, accordingly, the local position only enables local operation via the MMI. The disabled position inhibits the control of objects. The control position setting is password-protected. The logic position setting allows the logic control position via the inputs BINLOCAL and BINREMOTE, which facilitates the flexible selection of control position. The status outputs can be used for an application-specific logic. Note: The control position setting, which can be selected when the function block is used, refers to selecting the disabled, local, remote or logic state The logic setting facilitates the digital control position The control position refers to the selected position, i.e. disabled, local or remote 2

Description of operation 2.1 General The control position state can be accessed via the parameter F002V Configuration As a default, the control position setting is in disabled state and can be changed via the MMI. If the device does not include an MMI, the position is automatically remote, provided the function block has not been instanced. In case the function block has been instanced in the Relay Configuration Tool, the control position setting is logic and can be changed by means of the digital inputs. In such a configuration, the BINLOCAL input should be FALSE. 2.3 Operation criteria Digital output combinations: Control position Output: LOCAL Output: REMOTE LOCAL ON OFF REMOTE OFF ON DISABLED OFF OFF If the control position setting is logic, the digital inputs have the following effect: Input Output BINLOCAL BINREMOTE LOCAL REMOTE ON OFF ON OFF OFF ON OFF ON ON ON OFF OFF OFF OFF OFF OFF The output signal BYPASS reflects the present status of the control bypass mode. The status of the global bypass mode can be activated via the parameter F002V004 for all control objects. The LOGIC output reflects the activation of the logic position via the parameter F002V007. The figure below describes the basic internal structure of the function block. 4

The data direction of the parameters defines the use of each parameter as follows: Data direction Description R, R/M Read only W Write only R/W Read and write The different event mask parameters (see section Control settings ) affect the visibility of events on the MMI or on serial communication (LON or SPA) as follows: Event mask 1 (FxxxV101/102) Event mask 2 (FxxxV103/104) Event mask 3 (FxxxV105/106) Event mask 4 (FxxxV107/108) SPA / MMI (LON) LON LON LON For example, if only the events E3, E4 and E5 are to be seen on the MMI of the relay terminal, the event mask value 56 ( ) is written to the Event mask 1 parameter (FxxxV101). In case a function block includes more than 32 events, there are two parameters instead of e.g. the Event mask 1 parameter: the parameter Event mask 1A (FxxxV101) covers the events and Event mask 1B (FxxxV102) the events
