AO810 3BSE008522R1 ABB Analog Output Module

Description

AO810 Steps to Create an EPROM
1. After installing an EEPROM in the PROM slot of the PLC, it can be used to develop applications
2. Develop and debug the program stored in RAM, and AO810 writes it into EEPROM.
3. Remove the EEPROM from the PLC and install it in the EPROM cautery, and use it as a motherboard to obtain
EPROMs or more.
4. Install a blank EPROM in the EPROM cautery and copy the program in the EEPROM to this blank
In EPROM
5. Install EPROM in the PROM slot of PLC and copy the contents of EPROM into RAM memory

The rear EPROM will become the backup memory of RAM memory installed in the template
Note: The CPU can be configured to automatically download the application program stored in the PROM device to RAM when the CPU is powered off
Memory. See Chapter 6 “Operation of Backup Battery without Memory”
watch out
AO810 If PROM is configured (in CPU configuration menu) as power up program resource and
The PROM device has no PROM slot, or a blank PROM is installed in the slot,
After power on again, an empty program will be copied to the CPU RAM memory and the original
Programs stored in RAM memory first will be lost, so it is best to avoid emergencies
Back up current programs frequently
1 The maximum IO capacity is 160 points 2 The maximum IO capacity is 320 points
3 The configurable range is 128 to 32640 words
4 The maximum number of configurable words (% R,% AQ,% AI) is 240K bytes
5 CPU352 and CPU374 are hardware based floating point operations, while other CPUs are firmware based floating point operations
User storage address (flag)
The data stored in the series 90-30 PLC program is marked by its storage address, and a flag is stored in the
For the data in PLC, a marker in the storage type needs to indicate its storage type and an accurate location
No.), for example:
%I00001 Indicate the address 1 in INPUT
%R00256 indicates the address 256 in the register
Difference between storage address and variable name
%Used to distinguish between storage address and variable name. For example,% I17 (or% I000017) is a storage address. In similar cases, I17 is
PLC thinks it is a variable name and can assign any storage address to AO810. For example, if there is a
The motor of “INFEED No.17” usually wants to be called I17 and I17 as a variable is called output coil
(% Q11) start the motor, this is OK, because PLC can distinguish variable name I17 (storage address is% Q11
And storage address% I17
