2.1 M+FX5UCPU-EN_ConnectionOpen
Description
[For normal completion]
i_bEN
o_bENO
o_bOK
o_bErr
o_uErrId
[For error completion]
i_bEN
o_bENO
o_bOK
o_bErr
o_uErrId
• This FB does not include the error recovery processing. Program the error recovery processing separately in accordance
with the required system operation.
• This FB uses the SP.SOCOPEN instruction.
• Turn off i_bEN (Execution command) after o_bOK (Normal completion) or o_bErr (Error completion) is turned on. By turning
off i_bEN (Execution command), o_bOK (Normal completion) or o_bErr (Error completion) is turned off and o_uErrId (Error
code) is cleared to 0. However, because the SP.SOCOPEN instruction which is a pulse instruction in the FB is used, if a write
is performed while the FB is executed, the instruction may not be executed, and o_bOK (Normal completion) and o_bErr
(Error completion) may not turn on. If this happens, turn i_bEN (Execute command) from off to on again.
• This FB cannot be used in an interrupt program.
• Do not use this FB in programs that are executed only once, such as a subroutine program or FOR-NEXT loop, because
i_bEN (Execution command) cannot be turned off and the normal operation cannot be acquired. Always use this FB in
programs that can turn off i_bEN (Execution command).
• If this FB is executed for the connection for which parameters are already set by "External Device Configuration", make
settings so that the parameters specified by this FB are overwritten.
• Every input must be provided with a value for proper FB operation.
• Set the module parameters in GX Works3 in accordance with the connected equipment and system. For the module
parameters, refer to the MELSEC iQ-F FX5 User's Manual (Ethernet Communication).
