HIMA F6706 Logic control module

If an Update Datagram message requests 6 or less bits or bytes of data, the RX3i will return a Completion Ack without Text Buffer. The protocol specifies that the returned data will be in the Completion Ack message, but it may not be present. GBC30 may not resume operation after power cycle In rare instances, a GBC30 in an expansion rack may not resume normal operation after a power cycle of either the expansion rack or the main rack. Configuration of third-party modules Do not specify a length of 0 in the configuration of a third-party module. The module will not work properly in the system. Power supply status after CPU firmware update The RX3i will report a “Loss of or missing option module” fault for the IC695PSD140 power supply following an update of CPU firmware. Also, the slot will appear empty in the programmer’s online status detail view. The power supply continues to operate normally. Power cycle to restore normal status reporting.

Power supply status after power cycling 

Rarely, turning a power supply on or off may not result in an add or loss fault. Also, the slot will appear empty in the programmer’s online status detail view. The power supply continues to operate normally. To restore normal status reporting, cycle the power. Don’t use multiple targets In a system in which the hardware configuration is stored from one target and logic is stored from a different target, powering-up from flash will not work. The observed behavior is that, following a power up from flash, PME reports hardware configuration and logic "not equal". Missing “Loss of terminal block” fault The IC695ALG600/608/616 analog input modules do not produce a “Loss of terminal block” fault when hardware configuration is stored or the module is hot-inserted, and the terminal block is not locked into place.

Sequence Store Failure 

When downloading projects with very large hardware configuration or which use large amounts of user memory, it is possible to encounter a “PLC Sequence Store Failure” error when writing the project to flash. To avoid this error, either or both of the following actions may be helpful: 1. Perform an explicit clear of flash prior to performing the write. 2. Increase the operation timeout used by ME prior to performing the write. This is done by expanding the Additional Configuration in the Inspector window for the target controller, and adjusting Request Timeout. The timeout may need to be increased to as much as 60000 msec, depending on the amount of memory used and the condition of the flash memory. IC694MDL754: must configure module status bits Always configure 16 bits of module status when using this module. Configuring 0 bits of module status will result in invalid data in the module’s ESCP status bits.
