Product Introduction
88TK05C-E GJR2393200R1210 is used in stations belonging to the PROCONTROL system. In conjunction with the remote-bus coupling module 88FT05, it is used for coupling a PROCONTROL station to the remote bus. Moreover, the module controls all operations that are required to exchange data within a PROCONTROL station.

Product Details
Features:
88TK05C-E is equipped with
-One standard interface (SS) with the station bus
-One RS485 interface with remote-bus coupling module 88FTO5
-One module data interface with the remote-bus coupling module 88FT05
-One potential-isolated monitoring interface-One interface for dual-channel station-bus coupling-One input for operating the transmitter output stages in remote-bus coupling module 88FT05.
The module uses module addresses 60 or 61 (depending on whether it is intended for single-channel or dual-channel mode) as well as module address 62 (cf. chapter on 'Setting the station, system and module addresses')
The module can be plugged into any slot of the PROCONTROL cabinet. In the standard cabinets, however, reserved slots are provided.
Error-free telegram transfer between the 88Tk05 and older PROCONTROL modules located in the same station is ensured only if these modules have been manufactured after 1987 (serial nos. 9xx8 and higher).
For sending data communication, two main modes are available, which are controlled by the communication controller:
-Cyclic mode
-Event mode.
In the cyclic mode, the communication controller polls thestations one by one. This call for sending data telegrams isevaluated by the 88TK05 and is forwarded to the station.
In event mode, the 88TK05 signals the presence of events in the station by activating the noise channel. Then, the communication controller identifies the requesting station and generates an event call, which is evaluated by the 88TK05 and forwarded to the station.
The 88TK05 sends the cyclic or event telegrams provided by the station modules after polling. Transmission is via the 88FT05 to the remote bus.
All telegrams are checked for formal correctness and accuracy. Rate the contents. If an error is detected, the telegram is retained, and the 88TK05 sends a diagnosis telegram instead.
Until the next call, the 88TK05 module buffers each block of telegrams sent from the station for repeated transmission, in case the communication controller receives an erroneous telegram or if a sent telegram does not arrive at all.
Station-bus communication
Data communication with the station follows a defined protocol.
Col, which is controlled by the 88Tk05.
All PROCONTROL station modules follow this protocol; no module of the station may actively participate in data transfer without permission.
Protocol control mainly comprises the following functions:
-Identifying those modules that request a permit to send.Sending data telegrams to the station bus,
-Granting a sending permit for one station module at a time for sending data telegrams to the station bus,
-Enabling or disabling a sent or received data telegram after it has been checked for proper contents and formal accuracy,
-Controlling cyclic mode within the station:
In cyclic mode, all modules belonging to one station are granted, one by one, a permit to send their cyclic datastarting with the highest module address. The send permit is effective until all data has been sent.
