Data Array For Event-Oriented Data Channel - Bosch Rexroth ID 40 Manual

Table of Contents

The following functions have been completed when the counter value changes:

• Pretransmit data has been entered in the MDT (if parameterized)

• Prefetch data was read from the MDT (if parameterized) and is ready to be

imported to a PLC DB

• If auto reconnect is active, the MDT was closed and the link state is CONNECTING

• If auto disconnect is active, the MDT was closed and the link state is

DISCONNECTED

• If no auto mode is active, the link state is CONNECTED. Data can be exchanged

with the MDT.

Table 15: Status byte 01 of event-oriented data exchange

Byte 1 (bits 0–7)

Actual link state

Bit 0 shows the status of the SLK operative flag, see Chapter 5.3.4.

Bits 1 and 2 show the current status of prefetch parameterization. The flags apply

both to the unbuffered prefetch function and the buffered prefetch.

Bit 1 Prefetch is parameterized:

'0' = no prefetch currently parameterized in system

'1' = at least one unbuffered prefetch or one buffered prefetch is parameterized

Bit 2 Prefetch parameterization is open:

"0" = prefetch parameterization is closed. If prefetches have already been

parameterized, these are executed once the system completes the PRECONNECTED

state.

'1' = prefetch parameterization is open. No prefetches are executed in this state.

Bit 3 Data transfer status (see Chapter 6.6 "'Open transfer' and 'Close transfer'

functions"):

'1' = "Open transfer" command executed

'0' = "Close transfer" command executed

Bits 7 to 7 show the actual link state (see Chapter 5.3.1 "Actual link state").
