AH500 Module Manual

F4  GPIO detection error 
If the error still exists after repowering 
AH10PFBS-5A, replace it with a new 
AH10PFBS-5A. 
F5 
AH10PFBS-5A enters the mode of 
factory test. 
Repower AH10PFBS-5A after setting 
its node address between 1~125. 
F6 
1.  AH10PFBS-5A has not been 
connected to the PROFIBUS-
DP network. 
2.  PROFIBUS-DP master has 
not configured AH10PFB 
slave or the configured node 
address of AH10PFBS-5A is 
inconsistent with that of the 
actually connected one. 
1.  Check if the communication cable 
between AH10PFBS-5A and 
PROFIBUS-DP master is in normal 
status. 
2.  Ensure that AH10PFBS-5A slave 
has been configured to PROFIBUS-
DP master and the configured node 
address of AH10PFBS-5A is 
consistent with that of the actually 
connected one. 
3.  Check if PROFIBUS-DP master 
works normally. 
 
  The display mechanism of the digital displayer: 
1.  When AH10PFBS-5A is in normal state and the CPU module is in RUN state, the digital 
displayer of AH10PFBS-5A only displays the node address. 
2.  When AH10PFBS-5A is in normal state and the CPU module is in STOP state, the digital 
displayer of AH10PFBS-5A displays the node address and 80 (the STOP state code of the 
CPU module) alternately. 
3.  When AH10PFBS-5A is initializing or in error state and the CPU module is in RUN state, 
the digital displayer of AH10PFBS-5A displays the node address, initialization code and 
error code alternately. 
4.  When AH10PFBS-5A is initializing or in error state and the CPU module is in STOP state, 
the digital displayer of AH10PFBS-5A displays the node address, initialization code and 80   
(the STOP state code of the CPU module) alternately. 
 
13.8.3  State Register in AH10PFBS-5A 
The state register in AH10PFBS-5A is used for judging whether the current status of AH10PFBS-
5A is normal. 
AH10PFBS-5A can specify the state register in hardware configuration via ISPSoft.   
Double click AH10PFBS-5A icon in HWCONFIG and “Parameter Setting” dialog box pops up then.   
Click “Conversion Flags (Read only)” in the left-side blue box as below; then click what the mouse 
refers to in “Parameter Setting” dialog box; and then the “Address” dialog box appears immediately, 
where input the number of the specified state register e.g. the input 200 indicates that D200 is the 
state register.   
AH10PFBS-5A can only specify D device as its state register.
