Change of the specification of 3MB SRAM module in
S16i/18i/160i/180i/160is/180is-MODEL A and S15i-MODEL A/B
Abstract
In FS16i/18i/160i/180i/160is/180is-MODEL A and FS15i-MODEL A/B, FANUC will apply a new 3MB
SRAM module to systems provided from September 2005. Because FANUC adopt the ECC check
function instead of the parity check function for increasing reliability of the data stored in the memory.
It is unnecessary to change an order as the order specification is not changed. But please order the
new module in case of ordering 3MB SRAM module itself for maintenance.
FANUC will stop manufacturing the former 3MB SRAM module after this change.
FANUC has already adopted the ECC check function in the other SRAM module.
