FS-8704-13 GE-SRTP Driver Manual 1. GE-SRTP Driver Description The GE-SRTP driver allows the FieldServer to transfer data to and from devices over Ethernet using GE-SRTP Driver protocol. There are two Ethernet ports standard on the FieldServer. The FieldServer can emulate either a Server or Client. The GE-SRTP driver is capable of read & writing the data tables of a GE series 90 PLC which is equipped with an Ethernet port. The driver is capable of exposing its communication

FS-8704-13 GE-SRTP Driver Manual 3. Hardware Connections Make sure the device IP_address is configured to be on the same IP network as on the FieldServer. Use a crossover cable if the FieldServer is connected directly to the PLC device. Use a straight cable if the FieldServer is connected to a hub.

FS-8704-13 GE-SRTP Driver Manual 4.4.4 Map Descriptor Example 1 – Simple Read. This example provides a map descriptor to read 10 bytes of Discrete Input states, starting at the very first Discrete Input. The data is stored in a data array st called DA_DI and the first input is stored at location 100 in the array (101 element). The PLC is polled every 2 seconds Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Function, Scan_Interval, node_name, Address, Length, Data_Type CMD_AI_

FS-8704-13 GE-SRTP Driver Manual 4.4.6 Map Descriptor Example 3 – Handling Bits. This example shows how to read 1 couple of bits from a data table rather than reading a whole byte. The bits can cross byte boundaries. Here we read 2 bits from table %T starting at bit 8. This is most useful when writing to the PLC in cases where you want to turn one particular bit on or off.

FS-8704-13 GE-SRTP Driver Manual 6. Driver Notes 6.1 Driver Stats The statistics recorded by the GE-SNPX Serial Driver are slightly different from the way that Fieldserver driver normally record statistics. This difference arises from the fact that this driver is not a simple poll response driver. Bare in mind that a single poll can generate a large number of response fragments. Fragment Ack/nack messages are NOT counted as message but the bytes sent/rcvd are counted. Connection m
