PIUNSOL.INI
The Pyramid Integrator 5820-EI module can forward unsolicited messages from Allen-Bradley processors connected to the DH/DH+ ports of the Pyramid Integrator 5130-RM and 5130-KA modules.
INTERCHANGE C API clients could register directly with the 5820-EI module to receive these unsolicited messages. RSLinx Classic C API does not provide a means to register directly with the 5820-EI module to receive these unsolicited messages. RSLinx Classic can register directly with 5820-EI modules. These registrations are specified the piunsol.ini file. Piunsol.ini must be created in the same directory as the RSLinx Classic application executable.
Piunsol.ini does not change the RSLinx Classic C API applications. They continue to register for PLC-2 memory address unsolicited messages using the existing RSLinx Classic C API functions. This RSLinx Classic application's registration with the 5820-EI is completely independent from the RSLinx Classic C API application's registration with the RSLinx Classic application. For an RSLinx Classic C API application to receive PLC-2 memory address unsolicited messages from Pyramid Integrator DH/DH+ ports, both registrations must occur.
TIP:
- The 5820-EI module only forwards messages that match both the PLC-2 memory address and the message size.
- The same address can appear in more than on 5820-EI entry, and multiple entries can have the same or different size.
- Only PLC-2 read and write messages can be received.
- This feature does not add an "exclusive access" capability like the INTERCHANGE DTL_UNSOL_GETALL function.
