Description of functions

The serial interface terminal KL6001 enables the connection of devices
featuring an RS232C interface (for example bar code scanner). Regardless
of the higher-level bus system, data can be exchanged with the controller
in full duplex mode. The receive buffer is 128 bytes large, while the send
buffer embraces 16 bytes. Data transfer between the terminal and control­ler is handled via a handshake in the status and control byte. The termi­nal’s works setting is 9600 baud, 8 data bits, 1 stop bit, no parity, RTS/CTS
Control active.

The Run LED indicates the operating state of the terminal.
On – normal operation

Off – watchdog timer overflow has occurred. The green LED goes off if no
process data is transferred from the bus coupler for 100 ms.

The TxD and RxD LEDs indicate the states of the signal lines.

2 bytes of control / status byte) are mapped in the bus coupler. When de­livered, the KL6001 is set to the alternative format. Mapping of the terminal
in the alternative format is described in further detail in the chapter entitled
"Terminal Configuration".

By default, in the standard output format 4 bytes (3 bytes of user data and
1 control / status byte) are mapped in the bus coupler. Up to 5 bytes of
user data can be transferred by redefining the parameters of the KL6001.

The annex contains an over view of possible mapping configurations de­pending on the parameters that can be set.

Terminal configuration

The terminal can be configured and parametrized via the internal register
structure.

Each terminal channel is mapped in the bus coupler. The data of the termi­nal is mapped differently in the memory of the bus coupler depending on
the type of the bus coupler and on the set mapping configuration (eg Mo­torola / Intel format, word alignment.

For parametrization of a terminal, the control / status byte must also be
mapped.

When using the Beckhoff Lightbus coupler BK2000, the control / status
byte is always mapped in additon to the data bytes. It is always in the low
byte at the offset address of the terminal channel. In the case of the
KL6001 the C/S byte is only used in the register mode. The serial C/S byte
is used for the protocol.
