RCU501 is a Remote Controller Unit (RCU) based on a
PowerPC andremote I/O-bus interfaces. It runs the application
program of a process control system and interfaces to different
bus systems. RCU501 is provided with network interfaces for
redundancy conÞgurations
The RCU501 provides alarm functions such as:
Fan alarm
Temperature alarm
Voltage alarm
Controls, indicators and system connector
The RCU501 is provided with the NMI and RESET function
controls/buttons located in the upper right-hand corner of the
module.
Figure 2 NMI and RESET buttons layout
2.1.1 NMI push-button
Pressing the NMI function button stops the program execution
momentary.
NMI(Non-Maskable Interrupt) is also generated when watchdog
state is “watchdog_off”.
2.1.2 RESET push-button
Pressing the RESET function button restarts the program
execution and all parameter values are reset to initial values.
Reset will also be generated at power on and by software
generated reset.
2.1.3 RCU condition monitoring
2.1.3.1 Fan and over-temperature status
Two internal alarm signals are monitored by the module:
Fan-not-running alarm
High temperature alarm
2.1.4 Address switches (MAC 1. MAC 2.
MAC 3)
The RCU501 has three hexadecimal switches MAC 1 (S7),
MAC2(S6), MAC 3 (S5) by which you can set the MAC
address for NET A and NET B
MACaddress format for NET A is: 02:41:4C:42:1X:XX
MACaddress format for NET B is: 02:41:4C:42:2X:XX
where X:XX is MAC 1:MAC 2 MAC 3.
2.1.4.1 Example of address setting
The hexadecimal switch settings:
MAC1=1.MAC2=2.MAC3=3
give the MAC addresses:
NET A: 02:41:4C:42:11:23
NET B: 02:41:4C:42:21:23.
2.1.5 MODE switch
The RCU501 has a hexadecimal MODE switch (S4) (see Figure
3 on page 10), which is used to set operational mode. It is used
for ßashing resident application programs to the ßash memory
and for advanced servicing and debugging purposes.
Note
The switch has to be set to 0 (zero) for normal operation (default
setting).
2.1.6 LED indicators
2.1.6.1 Run/Error LED
The Run/Error LED is located on the front cover. It can be red or
green
