Checking triggering and data output in No Handshake mode:

Triggering and monitoring of the data output can be performed easily using a variable table. In the

No Handshake mode, no program or function module is necessary.

Addressing selected in the example:

Trigger bit:

Q1.0 Bit 0 of Adr + 1 of "Ctrl Bits Out"

Counter for data:

from IB 256: Adr of "32 Byte Input"

User data:

from IB 261: Adr + 5 of "32 Byte Input"

Variable table:

The scanner can be controlled by setting the A1.0 bits marked in red:

1  Trigger on, 0  Trigger off

In the first byte EB256, Bit 2 is inverted every second (heartbeat bit).

The user data is visible in the area outlined in blue.

The "Receive Count" counter increments with each block of data received. On overflow, the 0 is

skipped: 1 to 255, 1 to 255.

In the example, eight data bytes were received, with the content "12345678".

For more details on data reception, see Chapter 5.2.
