PD 601x DPI with RS232 Interface
Specific FeaturesA PD 601 DPI is used to provide local programmable intelligence for the local cluster connected via Light-Link P-NET, and to provide an interface with MODEMs, PCs or other serial equipment, such as printers, bar code readers etc. It uses the BM 003 or BM 011 base module. Communication interfacesThe PD 601 has 2 standard P-NET Communication Channels.
In the PD 601 DPI, Channel 1 is a P-NET RS232 communication channel, primarily for communicating with MODEMs or PCs, but also with other serial devices such as bar code readers and printers.
Channel 2 is a P-NET Light-Link communication channel intended for communicating with other locally mounted P-NET devices using the optical Light-Link interface. See General Distributed Process Intelligence information for a general description of the DPI family.
ProgrammingThe PD 601 is programmed in Process-Pascal, which is an extension of standard Pascal, allowing easy declaration and utilisation of P-NET variables and objects. Programs are developed and compiled on a standard PC, then downloaded directly via a P-NET interface. Program code can be downloaded to FLASH memory.
The PD 601 DPI devices have the channels shown in the following table.
See Variables outside channels
MemoryThe PD 601 DPI is available with 4 different memory versions: Small, Medium, Medium+ and Large. The amount and type of memory for each version is shown in the table.

VIGO LicenceWhen the FLASH operating system is running in the PD 601, it can give licence to run VIGO version 5.3 or higher on a PC connected directly to the PD 601 via the RS232 interface.
