通訊時(shí)PROFINET側(cè)如果有輸出數(shù)據(jù)變化,在MODBUS主站模式下串口側(cè)會(huì)以MODBUS RTU標(biāo)準(zhǔn)協(xié)議0x10指令寫多個(gè)寄存器,如果從站沒(méi)有正確應(yīng)答則會(huì)一直輸出,寫寄存器長(zhǎng)度為所選輸出插槽字節(jié)數(shù)除以2(最大為250 字節(jié)/2,或者為64字節(jié)/2),寫寄存器起始地址為參數(shù)設(shè)置的槽輸出起始地址(默認(rèn)為0);輸出指令示意:01 10 00 00 00 7D FA 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 40 79;
此條指令表示從寄存器地址0開(kāi)始連續(xù)寫125個(gè)寄存器;
2.讀數(shù)據(jù)說(shuō)明
通訊時(shí)PROFINET側(cè)輸入數(shù)據(jù)實(shí)時(shí)更新,在MODBUS主站模式下串口側(cè)會(huì)以MODBUS RTU標(biāo)準(zhǔn)協(xié)議0x03指令周期性讀輸入寄存器,周期時(shí)間可在模塊參數(shù)配置輪詢延時(shí)時(shí)間,配置為0時(shí)關(guān)閉讀寄存器指令;讀寄存器長(zhǎng)度為所選輸入插槽字節(jié)數(shù)除以2(最大為250 字節(jié)/2,或者為64字節(jié)/2),讀寄存器起始地址為參數(shù)設(shè)置的槽輸入起始地址(默認(rèn)為0);輸出指令示意: 01 03 00 00 00 7D 85 EB ;此條指令表示讀從寄存器地址0開(kāi)始連續(xù)讀125個(gè)寄存器;
特別說(shuō)明:主站讀從站寄存器時(shí),從站可根據(jù)實(shí)際應(yīng)用返回實(shí)際的數(shù)據(jù)長(zhǎng)度和內(nèi)容,所以返回?cái)?shù)據(jù)長(zhǎng)度和主站讀數(shù)據(jù)長(zhǎng)度可以不相同,以便節(jié)約從站內(nèi)存資源。
