SNP Slave Modules |
|
HE693SNP940 These Series 90-30 modules are SNP interface modules which allow an additional SNP slave port to be added to any Series 90-30 PLC. The SNP900 is the standard available model while the SNP940 is equipped with an internal 14.4kbaud modem. The SNP modules expand the capability of the PLC to support multiple SNP masters. The SNP port provided is configurable for either RS-232 or RS-485 operation. These modules allow a SNP master device to access Series 90-30 PLC reference data as though it were connected directly to the PLC's programming port. SNP messages may access up to 10,000 bytes of data in a single request. Datagram requests are supported up to a limit of 250 bytes per request. SNPX protocol is also supported. Configuration of the port type, associated serial protocol parameters and hardware handshaking is easily accomplished through either the GE Fanuc Hand Held Programmer or Logicmasterª 90. The module requires that the associated Series 90-30 PLC be version 5.01 or greater. Use of Logicmaster 90 for program uploading and downloading through the module is supported in CPU version 6.5 or greater. Uploading and downloading of Logicmaster 90 system configuration is not recommended.

| The SNP Protocol is a proprietary serial communications protocol developed by GE Fanuc for communication between PLCs and related equipment. The protocol is a set of rules that establish and maintain a communication link between a SNP master and a SNP slave device. SNP is typically a half-duplex protocol that uses either RS-485 or RS-232 electrical interfaces which are both provided by this module. SNP also allows the serial communications characteristics such as baud rate, parity and stop bits to be variable. |
