RTC_MemModule

Overview:

The INC RTC/Memory Module allows the user of a CANopen or DeviceNet network to store and retrieve data and the actual time and date. The RTC/Memory Module maintains the time and date during power down using an internal battery. The time and date can be read in the CANopen defined TIME_OF_DAY format or read/written in ASCII format. The user can store data to and retrieve data from the internal flash memory. The memory features allow the RTC/Memory module to act like a file storage device. Internal read and write file pointers automatically advance after a read or write to free the user to read and write data without having to worry about internal addressing. The RTC/Memory Module can store up to 392k. Memory writes are buffered in RAM and then maintained in flash memory for further data protection. An optional daughter board allows the use of up to four SD/Multimedia cards to store up to 1GB each. The RTC/Memory Module includes a Windows based configuration tool that allows the time and date to be set and retrieved, configuration to be set, and memory contents uploaded to a file. The configuration can then be downloaded to the display using one of several supported CANopen interface cards. The RTC/Memory Module can also be configured using the included EDS file or through SDO commands. The RTC/Memory Module can support up to 4 TxPDOs and 4 RxPDOS.

The unit has a USB connection and a DB9 connector for the RS232 connection. The CAN Network connector is available in a standard low cost 5 pin Combicon connector with screw flanges, or an optional 5 pin sealed micro connector. The Combicon connector allows the use of lower cost cabling, and also allows the use of a dual row Combicon plug to facilitate the daisy chaining of modules in the network. Options include a battery backed real time clock that allows the unit to timestamp all incoming CAN messages, and a connector that supports SD/MMC Cards. SD cards up to 2GB are supported that can be used to log CAN data for data analysis or troubleshooting.
