(a) Function
1) Changes variable size of P2P parameter block and destination station’s device area to read
(Command type Single and Continuous are available.)
2) After designating P2P parameter, block and variable by using P_NUM, BL_NUM, VAL_NUM, it changes the variable size
and device to VAL_SIZE(if continuous, VAL_SIZE means variable size and if individual, it means the size of variable type),
where DEV can be input only for a direct variable(ex, %MW100).
Communication modules: FEnet, FDEnet, Cnet
(b) Error
1) If it is out of the allowable scope of P2P parameter set in XG5000, the error number occurs as follows.
STAT_NUM
Message Description
1
P2P number setting
error If a value except P_NUM(1~8) is set
2
Block number setting
error If a value except BL_NUM(0~63) is set
< In case of Cnet, 0~31 >
3
Variable number setting
error If a variable number not allowed in P2P parameter set in XG5000 is
input
4
No slot -
5
Module inconsistency No communication module
6
Module inconsistency Communication module not available in the instruction
10 MODBUS setting error
MODBUS offset can not be input(ex, h10000). Because DEV can be
input only for a direct variable
11
Variable size setting
error
If a variable size not allowed in P2P parameter set in XG5000 is input
12 Data type setting error If a variable type not allowed in P2P parameter set in XG5000 is input
