b SoftPAC cannot communicate through serial ports on the PC.
c Serial ports are software configurable for RS-232 or RS-485.
d SoftPAC includes Status Read, Status Write, and Scratch Pad areas of the memory map.
e Function of Flash memory is implemented via a file; size is limited only by available disk space.
f Models manufactured before August 2007 and S1s with serial numbers 625653 and lower have 3-volt CR2032 lithium battery.
g This part is Obsolete, please contact Opto 22 Pre-Sales Engineering for more information.
h Requires firmware 9.4a or higher and loader 6.1a or higher for 32GB capacity; lower versions limited to 2GB.
i Units with serial numbers lower than 500,000 have an 8-24 VDC input voltage rating. Verfiy voltage on the unit's faceplate before applying power.
m I/O features vary by model. For details, see form 1677, SNAP PAC Controller and Brain Comparison Chart.
n All SNAP-RAC-R1-Bs, and SNAP-PAC-R1s with serial numbers lower than 600,000 are limited to eight 4-channel digital modules per rack.
p Only applies to SNAP-PAC-R1-B (Obsolete) |
