COM 265 Services and File Functions
11.1.1 Invoking the Symbols Editor
COM 265 is equipped with a special symbols editor which makes it possible to enter operand
commentary and symbolic operand identifiers from the IP 265 user program in an assignment list.
You will find detailed information on reorganizing the operand references in the assignment list and
removing operands from the list in Section 9.4.2, "Entries in the Local IP 265 Assignment List".
11.1.2 Loading the IP 265 Via the I/O Bus
For on-line testing, the IP 265 user program generated on the programmer can be loaded directly
into the IP 265. The load data for the user program is transferred over the CPU's PIQ and the
external I/O bus to the IP 265. To enable this, the programmer must be interfaced to the PLC (CPU).
Note
Only an IP 265 user program can be loaded into the IP 265. When a new user program
is loaded into the IP, it overwrites the "old" user program.
Prerequisites for starting the load procedure
• The programmer's program memory must contain an IP 265 user program that was generated
with COM 265 and compiled without errors.
• The IP 265 submodule receptacle must either be empty or contain an EEPROM memory
submodule.
• The following must have been entered in the COM 265 "Defaults" form:
- The current slot of the IP 265 to be loaded (e.g. "0")
- The filename of the IP 265 user program to be loaded into the IP 265 (e.g. "IP265")
• Because the I/O bus is serviced by the CPU, additional user actions may be necessary,
depending on the operational status of the CPU prior to COM 265 servicing. COM 265 provides
adequate support through appropriate messages and directives and prompts.
Note
COM 265 and the CPU both have access to the PIQ in CPU RAM. During loading, you
must ensure that no control commands or input parameters can be written by the CPU
user program to the PIQ ( Section 6.1, "Control of IP 265 Program Scanning").
