*1 3E frame, 4E frame, and station number extension frame are supported.
• Do not execute multiple SLMP commands simultaneously for one FPGA module. When using multiple
SLMP commands, send the next command after receiving the response message from the FPGA module. If
multiple SLMP commands are executed at the same time, the FPGA module may be unable to receive the
SLMP commands, and the SLMP commands may time out.
• When connecting multiple communication devices (such as the GOT and FPGA Module Configuration Tool)
to the FPGA module, actually communicate and adjust the execution interval so as to allow some leeway. If
the FPGA module cannot receive SLMP commands, an error such as timeout may occur.
