The y
hold
module contains a microprocessor which maintains serial data communication with the
processor on the main board through the Rxd/Txd lines. The processor feeds the U/I converter
and the CPU fault message output St
through its analog output. The module can be externally
supplied through an auxiliary voltage input which is OR--linked with the controller power supply.
The analog output of the module is freely available.
-y
hold
function
If data communication to the y
hold
processor is interrupted, the analog output receives its last
value. When data communication is restored, the slave processor reads the current variable
first. The output current is maintained if:
- the self--diagnostics of the CPU (see chapter 1.4.3, page 19) respond.
- the power supply of the SIPART fails and the y
hold
module is powered externally.
- all modules except the power supply unit are removed (if the y
hold
module is not powered
externally).
-they
hold
module is removed (Attention: electrostatically sensitive module! Observe the
safety precautions!), if it is powered externally (error message on the front module
oP. *.6 Err/oP.*.5, see chapter 1.4.3, page 19).
This makes it possible to carry out all service work up to changing the controller, e.g. in the
case of a controller (arithmetic block h0*.F), and to still maintain the controller manipulated
variable.
Handling during module replacement, see chapter 5, page 169.
-St
Fault message output
This digital output is always high when there is no error and becomes low in the event of an
error. It responds when:
- the self--diagnostics of the CPU (see chapter 1.4.3, page 19) respond.
- the controller power supply fails,
-they
hold
module is removed,
- the main board is removed.
6DR2802-8B Module with 3AA and 3BE
To extend the analog outputs (0/4 to 20 mA) and the digital inputs
Can be inserted in slot 5: AA4, AA5, AA6 BE5, BE6, BE7
and in slot 6: AA7, AA8, AA9 BE10, BE11, BE12
6DR2803-8P Interf ace PROFIBUS-DP
The module 6DR2803-8P is a PROFIBUS--DP interface module with RS 485 driver and electri-
cal isolation to the controller. It operates as an intelligent converter module and adapts the pri-
vate SIPART- to the open PROFIBUS-DP protocol.
This optional card can be inserted in all SIPART--DR controllers in slot 4. The following settings
must be made with the appropriate configurations for the serial interface:
