Storing (Downloading) Hardware Configuration
A PACSystems control system is configured by creating a configuration file using the PME programming
and configuration software, then transferring (downloading) the file from the programmer to the CPU via
serial port COM1, serial port COM2, or via an Ethernet port. If you use a serial port, it must be configured
as RTU Slave (default) or SNP Slave.
The CPU stores the configuration file in its non-volatile RAM memory. After the configuration is stored,
I/O scanning is enabled or disabled per the newly stored configuration parameters.
Before you can use an Ethernet Interface to store the hardware configuration to the PACSystems, you
must first set the IP Address in the Ethernet Interface either by using the Set Temporary IP Address utility
(refer to
Setting a Temporary IP Address
) or by downloading a hardware configuration through a serial
connection.
1)
In the programmer software, go to the
Project tab of the Navigator, right click the
Target, and choose Go Online.
2)
Right click the Target and choose Online
Commands, Set Programmer Mode. Make
sure the CPU is in STOP Mode.
3)
Right click the Target node, and choose
Download to Controller.
4)
In the Download to Controller dialog box,
select the items to download and click OK.
Notes:
If you download to a PACSystems target that already has a project on it, the existing project is
overwritten.
If I/O variables are configured, hardware configuration and logic cannot be stored independently.
They must be stored at the same time.
If passwords have been set, when you go online, you will be taken to the highest unprotected
level. If no passwords have been set, you will go online with Privilege Level 4.
