2 DEA 202 Features and Functions Product Overview The DEA-202 enables A120 series I/O modules to connect to the remote bus in an INTERBUS configuration. For the INTERBUS master, the DEA module is a remote node that can address up to 18 I/O modules (288 I/Os) via the subracks AS- HDTA200, AS- HDTA 201 or AS- HDTA 202. The DEA 202 comes with an integrated (non-isolated) power supply. It provides a 5 VDC supply at 1.6 A for the modules on the parallel I/O bus. The following figure shows the DEA 202 INTERBUS topology. Remote Bus DEA 202 DEA Station Remote Bus Addressing errors. CAUTION The DEA 202 module may cause addressing errors in INTERBUS configurations of generation 4. For this reason the DEA 202 must not be used together with INTERBUS Controller Boards of generation 4. Failure to follow this instruction can result in injury or equipment damage

3 Features The following list identifies key features of the DEA 202. l Coupling module with integrated power supply. l With the exception of intelligent modules, all analog and discrete Compact I/O modules can be employed. l The DEA 202 requires 1 word of the packet length for private data. Consequently, a maximum of 31 words remains available for use by the INTERBUS. l DIP switch default adjustment: Disconnection behavior as well as status and control word processing. Functional Details Watchdog The module serves as the coupling element between the remote bus (CPU connection) and PAB (connection to the I/O modules). The undervoltage monitoring signal from the primary and secondary voltages is evaluated internally by the module. The watchdog is a self-monitoring feature of the DEA. It consists of a monoflop with a delay time of about 320 ms. The DEA firmware performs an interrupt triggered control of the monoflop. After successfully powering on, which includes a successful EPROM check and initialization, the monoflop is triggered during program execution. The delay time of the monoflop cannot be changed. The green "ready" (watchdog) LED goes off if cycle times are greater than the monoflop s delay time. This condition activates the disconnection behavior as determined by DIP switches &

4 Module Faults The DEA 202 collects messages from the associated modules and reports these to the master as module faults (refer to the "DEA 202 Status and Fault Messages" section of the INTERBUS Quantum 140 NOA User Manual (P/N 840 USE ).

5 Configuration of the DEA 202 Overview The following information describes how to configure the DEA 202. DIP Switch Location and Settings The following figure shows the location and settings for the DIP switch. ON Note: For DEA 202 operation with the 140 NAO , all DIP switches (... ) must be in the "OFF" position. Status Processing () The following figure shows the status processing switch settings. OFF ON * As shipped Analog value processing with status and parameter* OFF ON Analog value processing without status and parameter

6 Control Word Processing () The following figure shows the control word processing switch settings. OFF ON DEA control word active. Required setting for 140 NOA Output begins after bus initialization completion.* * Delivery status OFF ON DEA control word inactive Required setting for 140 NOA and other Output begins immediately after startup. Disconnection Behavior (, ) The following figure shows the disconnection behavior switches and settings. OFF ON Master defaults are in effect (no defaults selected: All outputs are cutoff)* OFF ON Halt with value retention (outputs remain unchanged) Forced cutoff of all outputs Reserved for service specialists (Test bay setting) * As shipped, required setting for operation with a 140 NOA Note: and settings are meaningless. Subrack Mounting Slot The module is installed in DTA 200 primary subrack slot 1-1/1-2. When installing the module, be sure to adhere to the installation steps that are included in the accompanying documentation: Inter-Bus- -S Quantum 140 NOA User Manual (P/N 840 USE )
