_32BIT 32 bits
If the value of ErrorID is WORD#16#1C00, the CIP message error code is stored in ErrorIDEx. The
meaning and values of ErrorIDEx depend on the remote node. Refer to the manual for the remote
node.
Sending and Receiving Arrays
If ServiceDat or RespServiceDat is an array, pass a subscripted array element to it as the parameter.
Maximum Read/Write Data Size
You can read a maximum of 492 bytes of data. The maximum size of the data that you can write
depends on whether there is a request path attribute and the route path that is used, as given below.
Maximum write data size [bytes] = Base size − Attribute usage − Path information size
